Greetings to you, dear visitors! For the last couple of days I thought about the topic for the article, and then I came an email from one reader in which he asked to tell about the construction levels. And I thought - and an excellent thought. After all, where to repair without a level?
To date, the choice of levels is simply epic. From the simplest water to digital with a built-in laser. What level and for what purposes is needed, and also for what criteria to choose them - find out right now.
Construction level: Types
The most simple constructively is an ordinary water level, it is a hydrorette. It is two plastic usually cylindrical flasks with a scale connected to each other flexible long hose. The principle of his action is simple and should be understood by any high school student. It is based on a well-known physical phenomenon - the water level in the reporting vessels is always the same.
With this device, we can easily mark two points in one horizontal plane at the maximum distance equal to the length of the hose. You just need to put the marks in front of the water boundaries in the flasks.
Such a tool will be indispensable in the construction of a country house, markup of ceilings and floors when repairing and similar things. The length of the hoses of such levels lie in the range of 7 - 25 meters, which is quite a few. The cost of such a tool, understandable, is small, in the area of \u200b\u200b150 - 300 rubles.
It is more convenient to work with flasks of non-cylindrical shape, but with rectangular in cross section - it is easier to apply them to the surface. The diameter of the tube is the more, the faster the same level is installed in both flasks. As a rule, hydroeers have a diameter of 6 - 8 mm.
The following instrument class - bubble levels or waterpasses. Most has a length of 40 - 250 cm. The horizontal and the vertical in them is controlled by the position of the air bubble in alcohol, soldered in special transparent flasks. Short Waterpasa need when laying tiles, windows and windows mounting ...
Long - for setting beacons, check vertical / horizontal planes and lines, different marking. Oddly enough at first glance, Waterpasi may differ in many characteristics that we will talk more in more detail in the next chapter.
Cornelters and biasmen are devices that allow measurement and set the angles between the planes, and the slopes of the planes from the horizontal and vertical, respectively. Such devices may look different. Cornelizers are in the form of a quarter of a round of a circle and in the form of two "rails" connected by a hinge, or how it is there.
Basically, the angles and the bias are digital devices, that is, there are an LCD display where the angles are displayed. The inclusion is also often called an electronic or digital level.
I think that the tomitors are needed, mostly not builders, but to carpenters. They also will be more useful. In the finishing, the inclusiveness will only be in demand, perhaps on tile work, and more for control. Their highest accuracy (usually 0.05 degrees) does not leave the tile chance even on the smallest halter. And you will most likely beat up on the second or third tile))
My colleague, tiler, recently acquired a Bosch digital inclusion and confirmed it. But, the hell, how he is cool, this bosch.
There are also different avant-garde types of construction levels. For example, tube. They, besides, are still in different design. There are devices in the form of "hairpins", wear on the pipe, there are ordinary bubbles with a notch under the pipe on the housing, and there is generally the masterpieces of the avant-garde - "sticks" with five eyes, each of which is configured to a certain slope - to make it easier to conduct a sewer, you see Lee.
Laser levels. I already have an article about them, so I will be brief. This is the most technological look (I mean self-leveling). High accuracy, ease of use, huge time saving when marking. Such devices are divided into two large classes: positional and rotary.
Positioning does not have any moving mechanisms, as a rule, give a classic laser cross, or several points.
Rotary lasers provide one point, but it due to the spinning base quickly moves 360 degrees. Such instruments are used, for example, masters-ceiling.
Select bubble level
Of course, the most common tools for home repairs are bubble. So what criteria are the most important when choosing Waterpas?
First you need to decide what works you need it. From this will depend on the length of the tool. If for the tile, then you will not do with one level, you will need at least two: short (40 or 60 cm) and long (200 cm). Short is used constantly to check the level between adjacent tiles. Long - to control the entire facing plane.
If you intend to collect designs from GLC, plaster, pour the screed, you will definitely need a long Waterpas, at least two meters.
The next most important criterion is a form.
There are often levels in cross section representing rails. This is not the best choice - such a tool is very nervous. Much more powerful "stick" of a box type. And if inside them have a ribbiness - it is generally great!
The next point is the device of the flask.
Extremely important feature. In the store you can see the levels, let's say with such flasks: 
What do you think, in what case of the instrument readings will be more accurate? Of course, in the first. The smaller the distance from the borders of the bubble to the divisions of the flask, the more accurate the deviation can be determined. Remember this. Also pay attention to the sensitivity of the bubble, it strongly depends on the radius of the curvature of the flasks. It seems to the eye that the flask has the shape of the cylinder, but it is not entirely so, it is a bit twisted, otherwise the slightest deviation from the horizon "carried out" would be a bubble to the most edge of the flasks.
Here you can add another one. The flask for determining verticality is often unavailable for a good review, because Having attached the construction level to the wall, we will not be able to look at the level of the level parallel to it - the head interferes. So, we will not be able to objectively judge the testimony of the device. But there are levels in which a special mirror system is built, and the image of the flask "is output" to the rear end of the level, which is extremely convenient. Such a system have, for example, Israeli levels of Kapro Plumbsite series.
The accuracy of "sticks" for professional use is not worse than 0.5 mm per 1 meter length, and the tool is suitable for work on the house, with an accuracy of 1 mm per meter.
Processing workspaces. Ideally, they must be treated with a mill. This can be understood on a rough surface (-th).
The presence of embedded magnets is also a very important addition to any level. Having hung him to the profile and calmly regulate it. Even extremely useful "chips" of Waterpasov are slits in the building for the convenience of grip and rubberized lining, often employees also by shock absorbers in the event of a tool drop.
Rotary and adjustable flasks are controversial advantages. Tools for which manual adjustment is available instead of the "dead" fastening, most likely will be born. It is better to take once and forever sealed flasks. The main thing is to carefully check the tool in the store.
The verification procedure is quite simple. Put the level first on the table or counter, look at the testimony, remember. Then rotate 180 degrees (but that it remains in the same place!) And look again. If the bubble position is the same - the tool is not lying. The same procedure is done for the vertical, only attach it to the wall.
In some Waterpasa, the flask for controlling the horizontal is recessed in the middle. Personally, this decision seems uncomfortable to me, and I do not advise you to acquire a similar ***. The flask must be top, and the point.
Here is a good video about bubble levels:
Well, here, I told everything that I knew. Do not buy a frank cheap, carefully inspect the tool before purchasing. On this article is over, thanks for your attention! And do not forget to subscribe to updates.
When buying a construction level, you need to study it carefully. But to learn it, you need to know what to learn.
First of all, you need to pay attention to how the flask is located with a bubble. It must be absolutely smooth without any bends. If there is at least the slightest error, then when building it can hurt much.

Secondly, if you buy a level in the store, you need to test it immediately. Apply it to the wall, the floor. You must make sure that the level shows correctly.
I will tell you about one good way, how not to make a mistake when choosing a construction level, which I always use it myself. It is necessary to put it on any flat surface and mark on this surface with a marker (handle, pencil) labels, as it is worth it.
After that, it is necessary to turn it over 180 degrees and put in the same positions on marked tags. If the bubble in the flask is in the same position, as it was before, then the level is correct.
It is necessary to do the same for the vertical level. Similarly, we put it to the wall, the bubble must be in the middle. I turn over and put in the same position. If the bubble is on the same place the tool is correct.
Do not save on a construction tool, since most of the cheap levels calmly begged, which will be inconvenient when working.
- It is necessary to choose a sufficiently weighty level, it should not consist of some lightweight material.
- The bubble must move when the slope is smoothly without jerks and delays.
- There should be no extraneous objects and garbage in the bubble.
- The case must be thick enough.
- The walls should be about 3mm.
- If you work at the height, then you need to buy a level with a magnetic strip. Since it will be very convenient to live together to the surface and you will have loose hands.
To the level, it is necessary to properly treat enough, it is afraid of falls, as it is possible to deviate the bubble.
The bubble level is necessary for small and small work. For more large-scale work, it is necessary to use a laser level.
With a laser level, everything is much easier. You put it on a tripod, after which you are setting up manually, with the help of a bubble level, or you also include self-leveling at which it will configure himself.

With the help of a laser level, you can perform the same actions, but much faster. You just turn it on, set up one button and everything is ready.
Some laser levels have lasers that shine 360 \u200b\u200bdegrees. That is, you just put it in the center of the room and that's it.

Adjustment, setup, repair level repair. How to adjust it?
There are levels in which the ability to adjust. The sensitive element (flask with liquid) in such levels is fixed by a bolt.
If the bolt is weakened, then you can rotate the sensitive element, thereby configuring the level. Setup is usually made in one of two ways. Either we simply move the flask (such adjustment is less accurate), or an adjusting bolt is provided by turning, we adjust the position of the flask (more accurate adjustment is possible). Not all hydroversses are suitable for adjustment. There are those in which the flask is incurred. If such a tool is faulty, it must be thrown out.
Adjust the level does not make up problems if you have a strict horizontal surface.
But there is a vicious circle. To repair the construction level, a horizontal surface is needed, and a working level is needed to search for a horizontal surface. We obtain a horizontal surface with a broken alcohol.
We apply a stack of small pieces of paper, such as newspapers. Find a stable (motionless) approximately horizontal surface. We put our faulty level on it.
We will lay down a few pieces of paper under one end so that it will show the horizontality. We remember how much paper was put in this (first) time. Invert the level horizontally so that its right end is now to the left, and the left is right. If the level is working, it will continue to show the horizontality, since the good level shows the horizon, and the horizon is one that right to left, which is from left to right. If the level needs to be adjusted, then as a result of turning the air bubble in the flask will shift, the level will show that it is not horizontally.
We will lay a few more pieces of paper under one of the ends of the level so that it began to show horizontality again.
Perhaps you have to put the paper under the same end as last time, perhaps. At the same time, we consider every substrate piece. Now remove exactly half the pieces of paper attached at the second stage.
If there were an odd number, then rounded. Congratulations, we got a true horizon.
But the level shows the deviation. We release the locking screw, turn the flask so that it shown the horizontality, clamp the locking screw. Setup successfully completed.
Adjusting the vertical flask is performed completely similar. But for its execution you need an assistant, as it is performed on an approximately vertical wall.
And on such a wall, they will not hold onto the paper and the level. The assistant will have to hold them.
From a mathematical point of view, the proposed method is not completely accurate, but for the construction purposes an accommodation is acceptable.
Unfortunately, errors occur periodically in articles, they are corrected, the articles are complemented, developing new ones.

What level should I choose?
How to choose a building level? - Frequently asked question about each newcomer or ordinary citizen who decided to consolidate his own hands himself.
The spectrum of these tools in the modern world is very diverse. Today the market has many different types of levels from simple cheap to the most modern professionals.
But we need an accurate and reliable level. First, let's find out what their differences and consider each of them.
Water level (water level)
Builders are often called it - water level. It is used when it is necessary to detect deviations from horizontal surfaces. The principle of its work is based on the properties of water to establish a horizontal position in accordance with the law of communication vessels.
The water level is a tube up to 25 m long, at the ends of which there are bulbs with a scale.
Water is poured into the surface of the water, which leads to a noticeable weight.
- Prostate.
- Low cost (about 100-200 rubles).
- Ability to work with very large surfaces.
- When the level is filled with water, it is necessary to control the absence of air bubbles, otherwise the measurement error will be large.
- Do not use tools with heating devices.
- Only for horizontal surfaces is not possible work with vertical surfaces.
Bubble design level
This is the most common.
It consists of a body, in which several small glass flasks are closed with liquid. Depending on the number of lamps, it can be determined by horizontal accuracy (one flask), horizontal and vertical (containers), horizontal, vertical and inclined (three flasks) of the surface.
The most accurate level of bubbles, of course, is one with three flasks. Most often, the bubble has a rectangular layer size of 200 to 2500 mm.
The selection of length depends on the size and accuracy of applying to the surface.
The case of the level is made of light and powerful materials, such as aluminum, plastic, wood or polystyrene, and most often the alcohol is poured into the flasks. Some bubble levels are made using magnetic plates that help to handle metal products. They are also called magnetic levels. Sometimes a sign refers to one of the two bubble levels, for use as a ruler.
How to choose a type of construction bubble level?
Of course, it is better to focus on a good brand that produces professional tools.
For example, the construction level of the German company Stabila (costs about 600-1600 rubles). This company produces magnetic levels, as well as various devices that allow you to work with an electrician (there are special slots for marking a switch or socket).
For full measurements, level 600-700 mm, you do not need to buy a two-level level.
In addition to Stabile, you can also select Shark tools.
This indicator is not afraid to fall or get, it will not suffer. From the goods you can still buy: Bosch, Kapro or Ermak.
How to check the level of the building?
You must place the level on a smooth surface.
For example, it can be a desktop or a sales window. Remember your position, then place the second level in the same place. The bottle of the bulbs of one of them is likely to move aside. If this happens, remember the position of the bubble in accordance with the sections of the lamp.
Turn the tool to 180 degrees and insert it into the original position.
If the air bubble moves to the same position, the level is displayed correctly. If this does not happen, change the level to another and try new. You can also check any vertical level with water.
- Availability.
- Prevalence.
- Easy to use.
- Some allow measurement at an angle.
Pipe level
This type of level is also a bubble, but it has small differences.
They have less weight, some can reset. The pipe level is designed to work with pipes and profiles that are most often equipped with additional pipe mounting devices.
- Availability.
- Prevalence.
- Simplicity and practicality of work.
- There is a small probability of error.
Laser levels
Laser levels are the most accurate of all models represented.
These modern tools are very reliable and at the same time very expensive. Their prices range from 2000 to 18,000 rubles, depending on the manufacturer and multiple functions.
This is a very convenient and compact tool with high technical capabilities. The advantage is that the laser beam reaches length to 100 meters. If you are planning to purchase this type of level, it is better to choose reliable brands such as Bosch or Grosslaser.
- Easy to use.
- Very high accuracy.
- Compactness.
How to install and use the building level?
To properly manage the level of the building, you need to properly adjust it.
To do this, read the instructions. This is an individual for each brand and model, it contains all the necessary rules and recommendations. Some have a bicycle setup settings, others, if this electronic level is likely to configure automatic, you will need to select only the support system.
It is very important to follow the instructions, as even a new level has a certain error. Adjust the level correctly.
To properly adjust the hydraulic level, it is necessary to fill with water and observe the absence of air in thin pipes to zero bottles.
After this label lamps must be combined. If this does not happen, there are air bubbles or a tube transported somewhere. Do not fill the water level with ice or overwhelming water, the liquid must be at room temperature. This facilitates the uniform distribution of heat throughout the level loop, providing maximum measurement accuracy.
The bubble level requires careful treatment.
Class
This is a very delicate tool. Do not press it tightly, do not look or not flashes. It is enough just to apply it without effort to the surface, and if the surface is ideal, the air bubble will obviously be in the middle of the measuring signs.
Try to regularly check the accuracy of level measurement, since it has the ability to mislead.
Building levels: types, selection and purpose
Level is an indispensable tool when performing construction and installation work. It is necessary for the proper installation of doors, windows, styling of bricks and tiles, check vertical walls, horizontal floors. It is based on the installation of modern household appliances, communications.
The right choice of measuring instrument significantly improves the quality of work and saves time.
By design, five main types of building levels can be distinguished: bubbles, electronic, pipe, hydraulic, laser. Below we will look at each of them in more detail.
Five types of construction levels
Bubble levels They got the greatest distribution due to their simplicity, availability and versatility.
They are called so because they have a sensitive element of air bubble floating in ampoule. The error of measurements of these devices is 0.5 ÷ 1 mm / m. Domestic models are manufactured according to GOST 9416-83, which describes the technical conditions for their manufacture. The body of the tool is a hollow boxed design with rigidity ribs. It can have a length of 30 cm to several meters.
To reduce the mass, the device is made of aluminum alloys. Ampoules with air are closed with protective glass. At the base of the case, as a rule, there is a millimeter measurement scale.
Magnetic bubble levels are perfect for working with metal structures.
Their distinctive feature is the presence of built-in magnets that allow you to fix the tool vertically on metal details. For masonry, there are models with a reinforced cast case.
If you are coming plastering, pay attention to the rules with the level. They combine two devices in themselves at the same time.
Electronic levels A teller belongs to a professional measuring instrument.
They have several bubble chambers to estimate the verticality and horizontal structures. However, in contrast to the usual levels, such devices have a number of additional features.
One of the main features is a digital display, which clearly displays the deflection value in degrees.
In this case, the accuracy of the data provided is high - to 0.1⁰. It is possible to record measured slopes. A sound indication is provided that signals the achievement of 0⁰ and 90⁰.
Checking the accuracy of the electronic level is simple and does not take much time. To do this, you need to put the device on a flat surface, withdrawn.
Turning a level of 180 degrees, to see new meanings. If the difference in readings is more than 0.2⁰, the device is calibrated.
Pipe level Designed to check the horizontal and verticality of water supply, gas, sewer pipes.
In general, it is convenient to use it for working with beams, a round profile in various building structures. The main features of this tool are the V-shaped shape of the hull, the presence of magnets.
Thanks to this, the instrument can be easily installed on a metal pipe or support.
The pipe level, as well as bubble, is equipped with several flasks with alcohol liquid.
In each of them floats the air bubble, by the location of which the deviation from the specified direction is determined.
Hydraulic Used to apply accurate horizontal markup on the objects deleted from each other. With it, they make a panel of flooring, the installation of the foundation, the brick laying, the installation of various building structures in the same plane.
The hydrostatic level consists of two vessels interconnected by a transparent tube.
Before working, the system is filled with water so that it occupied approximately 2/3 of the volume of the flask. At the same time, the fluid inside the tube does not contain air bubbles. They need to be removed, otherwise the measurements will be inaccurate. Negleps and fractures of the tube are not allowed: water should flow freely from one vessel to another.
To check the accuracy of the device, the flasks combine each other. It is necessary that the boundaries of the liquid have a common one.
Industry produces hydrostatic levels from 5 to 25 m long. The error of measurement of these devices is 2 ÷ 3 mm. Marking is recommended from one basic tag. This allows you to achieve maximum accuracy.
Laser building levels (Leveliers) refer to the group of professional measuring instruments.
Despite the fairly high cost compared to other solutions, they provide their owner a number of advantages. First of all, it is a high accuracy markup. The magnitude of the allowable deviation is only 0.1 ÷ 1 mm / m, depending on the class of the instrument. The technical capabilities of linear laser levels allows them to build horizontal, vertical, as well as inclined planes at a distance of several tens of meters from the installation site.
For home use, this is more than enough. Rotary laser levels Thanks to the rotation of the emitter, the rays across the perimeter of the room are projected, that is, cover the entire space around itself.
What construction work is conducted using laser levels:
- alignment of walls or floor;
- installation of mounted equipment;
- wall pastry wallpaper;
- installation of stretch ceilings;
- facing of premises tile;
- installation of partitions and others.
How to choose a building level
To repair efficiently, before the start of work, choose a good measuring instrument.
Now there are a wide variety of building levels. They differ from each other by appointment, technical characteristics, manufacturing quality and price.
What task is before you?! If an inexpensive universal tool is needed for all occasions, it is worth paying attention to bubble levels.
They are comfortable, unpretentious, and most importantly - have good accuracy. Their capabilities are enough to put the tile, install windows, doors or furniture. The length of the universal level is 60 ÷ 80 cm.
Electronic levels with a tilter and magnetic system will suit those who decided to repair seriously.
They have advanced features. First of all, this is a visual representation of data on an electronic display with an accurate indication of deviations in degrees, percentages or millimeters. Other distinguishing features are high accuracy, the reading function, as well as the possibility of electronic calibration.
If you need to align beams, pillars, plumbing or gas pipes in vertical and horizontal directions, use all the advantages of pipe levels.
Their indisputable advantage is the possibility of accurate centering on these elements of building structures.
The water level will be useful when the floor screed device, the mounting of the suspended ceilings, the foundation device. It will come in handy for marking places for the socket, which will look aesthetic, being at one height.
How to choose a bubble construction level
Water level can perform accurate horizontal marking for related rooms, between which there is no direct visibility. This consists of one of its main advantages. This tool has low cost, easy to operate. Its length varies from 5 to 25 meters, which is quite enough for domestic use.
The laser level will be an excellent choice for those who have a large amount of construction work.
It will significantly save time, while ensuring the high accuracy of constructions of both horizontal and vertical planes. This is a good tool for blending the floor level, wall markup for finishing works, installation of furniture and communications.
Three main types of laser levels can be distinguished: point, linear, rotary. In accordance with the title, they are used to build dots, lines, as well as markups throughout the perimeter of the room at the same time.
Before starting work, laser devices must be aligned with the built-in bubble level.
Some models have an additional self-configuration function within 2 ÷ 4 degrees. The price of professional laser levels is high enough, however there are available options for home use.
What to pay attention to when choosing
Among the large number of manufacturers present in the measuring instrument market, there are those that have already managed to conquer an excellent reputation in our country and abroad.
In a good account, builders are bubble, as well as electronic levels of Stabila and Kapro. Bosch laser levels are known for their quality. However, it is best to rely on your own experience in order to purchase a thing with the necessary set of functions for reasonable money.
Basic selection criteria: specifications, equipment, quality assembly and materials.
By purchasing a bubble level, it is necessary to inspect its appearance. Are there any visible damage?! What are the quality of the materials, is it carefully assembled?! Special attention should be paid to ampos with liquid.
They must be securely embedded in the housing.
Put the selected level on a smooth horizontal surface. It must be tight, without gaps to lay down its base. Remember the position of the air bubble in the upper ampoule.
After that, turn the device to 180 ° C clientwise or counterclockwise and place the same place. If the bubble has shifted relative to the initial position, it is impossible to trust this level.
Similarly, you can check the accuracy of the readings vertically.

Laser Level (Level Level)
Possible difficulties with level
Those who are going to make overhaul in the apartment, the question of how to repel the level of the floor to be perfect.
But for this you must first determine how much the error and understand how many materials and items must be purchased. Fortunately, there are many options in the modern market, thanks to which you can qualitatively and without any particular problems to carry out work on alignment.
Methods and materials for measuring floor level
Each owner of the apartment or home independently chooses a scheme, on which the transformation of the surface of the lower part of the room will be carried out.
The question of how to set the floor level, acquires a special meaning in the case of:
- If the surface was previously aligned, but it remained excessive raw materials and were not seized;
- If errors were allowed during construction and the surface was originally uneven;
- If the floor level in a private house is not sufficient to introduce a new coating;
- If the house or apartment is old and the surface suffered due to chemicals or influence of external factors (floods, fungi, dampness).
In any of these situations, it is possible to fully determine how to check the floor level for the transformation of the apartment or home fully.
Based on the photo of the future of space repair, it is necessary to conclude, as far as it is necessary to raise the level of the lower surface of the room.
Options for how to measure the floor level, are a variety of, the main ones are:
- Measurement of the level as a hydraulic level (water level);
- Measurement of error in flatness surface with a laser (read also: "How to check the flattering floor: ways to check in practice");
- And also, measurement with the help of level, this option is used for more professionals.
Each of these options is suitable for its embodiment.
The owners can choose a suitable on the basis of:
- Price pricing device;
- Skills and experience;
- Technical side of the question.
Hydraulic
This level is a design consisting of:
- Rubber tube;
- Two containers at both ends of the product.
In working with such a device, you must act in a pair and step by step. As a rule, this method is as often as possible as among experienced builders and repairmen and among beginners.
Step-by-step actions on how to remove the floor level:
- First, it is necessary to pour the liquid into the rubber transparent tube, usually pour water. The tube must be so as far as it is planned to raise the floor;
- Then one of the participants in the repair work raises its end of the tube to the necessary height and where the water stops puts the mark on the wall surface;
- How to determine the floor of the floor will become clear when the second participant of repair reincublings will bring the tube to another end of the room.
It is necessary to wait a couple of seconds so that the fluid is fully leveled into the vessel. After that, also put the mark at the level where the water was stopped in the tube;
- The same manipulations can be performed with all other walls of the wall;
- After marks, you can slightly lower the level if it is too high.
To do this, you will need a special meter. In this case, it is necessary on both sides to reduce the level of the mark on the same number of centimeters so that the floor covering does not work too high.
- Water does not move on a hydraulic tube. In this case, the tool should be rinsed, maybe there are some stagnant sorts, in view of which the liquid does not move along the vessel. You can also blow the hydroelectric background so that unnecessary objects interfering with the normal functioning of the device.
- Water not at the same level.
Such a trouble may appear due to the formation of air bubbles. From them, you can get rid of the HYDROWER knob on the tube or re-gaining water under greater pressure.
Laser Level (Level Level)
Difficulties in the question of how to use a laser level for floor alignment, it should not arise.
The process of using such a method to determine the height of the surface is very simple.
The kit to this equipment includes:
- Installation, emitting laser rays;
- Tripod (nozzle);
- Stand, thanks to which you can vary the height of the device.
I have understood the scheme, how to check the floor level with a laser level, the process of work will take at all time and this feature is it possible to perform even single.
Step-by-step instructions How to beat off the floor level with a laser level:
- First, it is necessary to install the device. Depending on the cost, and therefore, the quality, tool, the installation process may be different. In budget models, the equipment will need to be directed to each wall in turn.
Best building levels for user reviews
In levels of laser installations, the lighting of laser drawings falls on the entire area of \u200b\u200bthe room;
- The second step is the drawing on the wall with a laser line.
This function can be carried out with the help of a special upholstery cord or using a ruler and pencil.
- After that, you can proceed to the level of alignment of the surface of the floor covering.
Possible difficulties with level
Determining the level of the floor with the laser (level) installation, is extremely difficult to be mistaken.
However, errors are possible in the case of:
- If the edges of the laser directions are unevenly exhibited;
- If when the boundaries are transferred to the surface of the wall, the wizard or the owner of the apartment apartment incorrectly inflicted the dashed;
- If the level is set too low or high.
Conclusion
When choosing any of the options for measuring the floor surface level, the result will be accurate.
The only thing is that the two of these measurements are distinguished, it is a level of difficulty in use:
- Laser installation is very easy to use and with it, the performance of work is reduced to minimal actions from the employee.
But the cost of this device is quite high from 5,000 to 20,000 Russian rubles.
- The hydroeer also allows you to clearly define the height of the surface. This device requires great effort from participants in repair. But you can make this installation even on your own, from the subwoofers, which can always be found in the storeroom or in the garage.
After carefully studying all the details and nuances of using the floor surface meters, it is possible to fully and perfectly implement the process of aligning the lower part of the room.
Construction level An indispensable working tool designed to test vertically and horizontally different surfaces. It is used at all stages of construction, ranging from the preparation of the foundation, and ending with the plaster of walls and laying outdoor coverage.
Types of construction levels
There are 5 species of levels that are used in construction and installation work. They are:
- Bubbles.
- Electronic.
- Pipe.
- Water.
- Laser.
Each species has its advantages and disadvantages. The choice in favor of a separate tool to greater extent depends on the operating conditions and scale of construction or finishing.
Advantages and disadvantages of bubble level
A bubble level is the most common. Often, in addition to the level function, it fulfills the task of the line. Usually the device is a flat rack, on which glass flasks with alcohol liquid are fixed. They have small air bubbles. The central flask serves to display the horizontal, and the two extremely located cross sections of the ruler show the vertical and 45 degrees. This is the easiest and most universal tool. It is used to check vertical and horizontal, for drawing marks, they use as a ruler and even as a rule. To check horizontals and verticals using such a tool, it is necessary to control the air bubble in the corresponding flask in the center.
Bubble devices are budget and very common. This level is made from the metal profile. You can find levels that are made of aluminum or steel on sale. Aluminum devices are better to avoid, because when their surface drops, the rigidity edges are bent or deformed. A bubble tool will be indispensable when making wall clips or plastering. Such levels are used as professional builders who can afford to purchase a more expensive tool and amateurs. This device has an error of approximately 1 mm per meter of length, but it is not so substantial.
The length of this level is the most diverse. The cheapest are short tools in a length of 30-40 cm. They are little in demand, since it is possible to determine deviations in the level only on an ideally flat surface. In the same way, if you need to work with a nonideal plane, on the surface of which there are minor drops around the perimeter, it is necessary to apply the level of long length. Bubble tools in 1 m long are bubble tools. On sale you can meet levels up to 4 m.
Often on the working surface of the level, which is applied to the measured plane, there is a permanent magnet. This allows it to be fixed on steel elements, such as beams and roofing sheets.
Bubble construction level has several advantages:
- Low cost.
- Resistance to mechanical damage.
- Universality.
- Easy to use.
- The ability to calibrate the flask.
The disadvantages of the tool include its massiveness. Such a level is difficult to use in small rooms, such as bathroom or storage room. In this case, you have to choose short devices that are characterized by less accuracy.
When buying a bubble level, it must be checked. For this, the tool is applied to any horizontal surface and the indicator that it shows is fixed. Next, the level must be deployed 180 degrees and compare the new position of the bubble with what was previously. If everything is still left, then the tool works as it should, and if the bubble is in another position, the level needs to be calibrated, which is accompanied by a number of inconvenience, so it is better to look for another. The flask for vertical measurements is also checked in the same way.
Electronic construction level
It is practically the same bubble, the exception that it is equipped with an electronic display, which shows the indicators of the angle of deviations from the norm. In individual tools there is an internal memory that saves data.
Such a tool is more expensive, but in some cases is more preferable. Due to its use, you can measure the volume of the material to be used to align the horizontal or vertical surface. This uses well-known geometric formulas. This appliance has a sound indication that reports that the perfect vertical or horizontal is achieved.
It is worth noting that the electronic building level allows to obtain measuring data with an error of only 0.1 degrees. The instrument sensor is not perfect, so the tool must be checked before purchase. If the error in the angle of horizontal or vertical inclination in one position in two directions with a difference of 180 degrees is only 0.2 units, then this is a completely suitable tool that can be bought.
Pipe level features
The pipe level is also a bubble design, but in an unusual form. Instead of rack, it is fixed in a small plastic corner 90 degrees. This tool is designed to check the tilt of pipes and beams. Thanks to the angular form, this tool is securely fixed on the surface, and it allows you to simultaneously control the horizontal and vertical.
Pipe level, although it has a short base, but since it is used in practically ideal planes, such as pipes and beams, therefore it has good accuracy. Often there is a magnet in its design, so it can work with metal surfaces without support. When purchasing it, it is also necessary to pre-check for the correspondence of the testimony of the bubble in the flask, depending on the direction of the instrument. Often the device is tied to the measured surface with a perforated tape, which comes in the kit. The unconditional advantages of such a tool include its compactness and maximum adaptation of the design for convenient work with pipes and beams. The only drawback that the pipe construction level possesses is that it is not suitable for another work.
Features of the hydroevores
Water building level is used to check the tilt of long horizontal surfaces. The device has 2 vessels made in the form of flasks that are connected with each other with a long flexible hose. Before applying the tool, the flasks are fixed in the same position at the same level, and filled with water. The liquid fills them together with the hose that connects them. Water floats until the hose is filled and the flasks themselves on 2/3 of their volume. Next, the flasks must be closed with special dense lids. The vessels are installed at the ends of the surface, which must be measured, after which covers open. This device works on the physical principle of the connected vessels. Atmospheric pressure levels the fluid column in the vessels to the same level. If in the first and second flask, the water pillar is at the same height, it means that the horizontal is achieved.
Hydraulic construction level is the cheapest. The length of its hose is usually from 5 to 25 m. The cost of the tool depends on the quality of the flask. When buying it is worth paying special attention to the material from which they are made and the density of the covers. If they are unreliable, then when filling the tool with water and stretching the hose to install the flask along the edges of the measured surface, the liquid can flow. The disadvantages of this equipment include its limited capabilities. With a rapid filling of flasks with water in the hose, air bubbles can appear, which brought the system and affect the accuracy of measurements. Often when storing the tool under the right sunlight, plastic transparency is lost, and it becomes yellow.
Advantages and disadvantages of the laser level
Laser building level is also called level. It is a professional equipment that does not simply allows you to define a vertical and horizontal, but also shines the surface with a laser beam, which allows you to spend over it or immediately navigate the luminous strip. Such equipment can be fixed in the center of the room, after which its body is exhibited smoothly with a bubble flask that is on its surface. Next, the device turns on, after which the laser rays outline the horizontal and vertical lines on the walls. Depending on the power level, the length of the luminous lines can be several tens of meters.
Laser building level is the most perfect. It gives the most accurate indicators and is distinguished by small dimensions, while it allows to work in rooms with a large area and even in very close storage rooms. With it, you can identify the slightest deviations on the measured surface. Laser levels are used by professional builders, since they significantly accelerate the workflow. The tool highlights perfectly vertical and horizontal lines, which allows finishing without prior drawing. With this level it is easier to lay wallpaper or floor tiles, glue wallpaper, fix the frame for drywall or stretch ceilings.
An explicit disadvantage of this equipment is its high cost. Those tools that have a more or less affordable price have low efficiency. Of course, they are accurate, but the laser built in them does not allow to illuminate a large room over the entire contour. In the daylight, luminous lines are practically invisible, and the process of setting the level itself before inclusion takes longer.
The right choice of measuring instrument significantly improves the quality of work and saves time. By design, five main types of building levels can be distinguished: bubbles, electronic, pipe, hydraulic, laser. Below we will look at each of them in more detail.
Five types of construction levels
Bubble levels They got the greatest distribution due to their simplicity, availability and versatility. They are called so because they have a sensitive element of air bubble floating in ampoule. The error of measurements of these devices is 0.5 ÷ 1 mm / m. Domestic models are manufactured according to GOST 9416-83, which describes the technical conditions for their manufacture. The body of the tool is a hollow boxed design with rigidity ribs. It can have a length of 30 cm to several meters. To reduce the mass, the device is made of aluminum alloys. Ampoules with air are closed with protective glass. At the base of the case, as a rule, there is a millimeter measurement scale.
Magnetic bubble levels are perfect for working with metal structures. Their distinctive feature is the presence of built-in magnets that allow you to fix the tool vertically on metal details. For masonry, there are models with a reinforced cast case. If you are coming plastering, pay attention to the rules with the level. They combine two devices in themselves at the same time.
Electronic levels A teller belongs to a professional measuring instrument. They have several bubble chambers to estimate the verticality and horizontal structures. However, in contrast to the usual levels, such devices have a number of additional features.
One of the main features is a digital display, which clearly displays the deflection value in degrees. In this case, the accuracy of the data provided is high - to 0.1⁰. It is possible to record measured slopes. A sound indication is provided that signals the achievement of 0⁰ and 90⁰.
Checking the accuracy of the electronic level is simple and does not take much time. To do this, you need to put the device on a flat surface, withdrawn. Turning a level of 180 degrees, to see new meanings. If the difference in readings is more than 0.2⁰, the device is calibrated.
Designed to check the horizontal and verticality of water supply, gas, sewer pipes. In general, it is convenient to use it for working with beams, a round profile in various building structures. The main features of this tool are the V-shaped shape of the hull, the presence of magnets. Thanks to this, the instrument can be easily installed on a metal pipe or support.
The pipe level, as well as bubble, is equipped with several flasks with alcohol liquid. In each of them floats the air bubble, by the location of which the deviation from the specified direction is determined.
Used to apply accurate horizontal markup on the objects deleted from each other. With it, they make a panel of flooring, the installation of the foundation, the brick laying, the installation of various building structures in the same plane.
The hydrostatic level consists of two vessels interconnected by a transparent tube. Before working, the system is filled with water so that it occupied approximately 2/3 of the volume of the flask. At the same time, the fluid inside the tube does not contain air bubbles. They need to be removed, otherwise the measurements will be inaccurate. Negleps and fractures of the tube are not allowed: water should flow freely from one vessel to another. To check the accuracy of the device, the flasks combine each other. It is necessary that the boundaries of the liquid have a common one.
Industry produces hydrostatic levels from 5 to 25 m long. The error of measurement of these devices is 2 ÷ 3 mm. Marking is recommended from one basic tag. This allows you to achieve maximum accuracy.
Laser building levels (Leveliers) refer to the group of professional measuring instruments. Despite the fairly high cost compared to other solutions, they provide their owner a number of advantages. First of all, it is a high accuracy markup. The magnitude of the allowable deviation is only 0.1 ÷ 1 mm / m, depending on the class of the instrument. The technical capabilities of linear laser levels allows them to build horizontal, vertical, as well as inclined planes at a distance of several tens of meters from the installation site. For home use, this is more than enough. Rotary laser levels Thanks to the rotation of the emitter, the rays across the perimeter of the room are projected, that is, cover the entire space around itself.
What construction work is conducted using laser levels:
- alignment of walls or floor;
- installation of mounted equipment;
- wall pastry wallpaper;
- installation of stretch ceilings;
- facing of premises tile;
- installation of partitions and others.
To repair efficiently, before the start of work, choose a good measuring instrument. Now there are a wide variety of building levels. They differ from each other by appointment, technical characteristics, manufacturing quality and price.
What task is before you?! If an inexpensive universal tool is needed for all occasions, it is worth paying attention to bubble levels. They are comfortable, unpretentious, and most importantly - have good accuracy. Their capabilities are enough to put the tile, install windows, doors or furniture. The length of the universal level is 60 ÷ 80 cm.
Electronic levels with a tilter and magnetic system will suit those who decided to repair seriously. They have advanced features. First of all, this is a visual representation of data on an electronic display with an accurate indication of deviations in degrees, percentages or millimeters. Other distinguishing features are high accuracy, the reading function, as well as the possibility of electronic calibration.
If you need to align beams, pillars, plumbing or gas pipes in vertical and horizontal directions, use all the advantages of pipe levels. Their indisputable advantage is the possibility of accurate centering on these elements of building structures.
The water level will be useful when the floor screed device, the mounting of the suspended ceilings, the foundation device. It will come in handy for marking places for the socket, which will look aesthetic, being at one height. Water level can perform accurate horizontal marking for related rooms, between which there is no direct visibility. This consists of one of its main advantages. This tool has low cost, easy to operate. Its length varies from 5 to 25 meters, which is quite enough for domestic use.
The laser level will be an excellent choice for those who have a large amount of construction work. It will significantly save time, while ensuring the high accuracy of constructions of both horizontal and vertical planes. This is a good tool for blending the floor level, wall markup for finishing works, installation of furniture and communications.
Three main types of laser levels can be distinguished: point, linear, rotary. In accordance with the title, they are used to build dots, lines, as well as markups throughout the perimeter of the room at the same time.
Before starting work, laser devices must be aligned with the built-in bubble level. Some models have an additional self-configuration function within 2 ÷ 4 degrees. The price of professional laser levels is high enough, however there are available options for home use.
What to pay attention to when choosing
Among the large number of manufacturers present in the measuring instrument market, there are those that have already managed to conquer an excellent reputation in our country and abroad. In a good account, builders are bubble, as well as electronic levels of Stabila and Kapro. Bosch laser levels are known for their quality. However, it is best to rely on your own experience in order to purchase a thing with the necessary set of functions for reasonable money. Basic selection criteria: specifications, equipment, quality assembly and materials.
By purchasing a bubble level, it is necessary to inspect its appearance. Are there any visible damage?! What are the quality of the materials, is it carefully assembled?! Special attention should be paid to ampos with liquid. They must be securely embedded in the housing.
Put the selected level on a smooth horizontal surface. It must be tight, without gaps to lay down its base. Remember the position of the air bubble in the upper ampoule. After that, turn the device to 180 ° C clientwise or counterclockwise and place the same place. If the bubble has shifted relative to the initial position, it is impossible to trust this level. Similarly, you can check the accuracy of the readings vertically.
Regular measurement and scrupulous control underlie all areas of construction. If an ideal result is needed in finishing or repair, markup and check of the geometry of structures are required. The normal owner will not hang the shelf or install a washing machine without measuring and control manipulations. They are performed using building levels used to comply with horizontal and vertical directions. These are fixtures and devices that differ in the degree of complexity, cost, purpose. The home master should be known which construction level is better, that it will be useful or may not be needed in the farm.
The ancestors of the building levels were Waterpas and plumb, since the ancient pores used by the builders for marking and control. The plumb is used to determine verticals, waterproof - horizontal.
The principle of operation of old uncomplicated devices is closely associated with the law of global gravity. The most important element of the simplest devices is an adulted steel dweller with a cone-shaped tip. Under the action of gravity, the metal item steadily strives down, without the slightest error, repeating the line of the vertical. Actually, the dweller is a plumb that is tritely suspended on the cord or a fishing line if you need to find or verify the vertical direction.
In Waterpas, the plumb is attached to the top of the equilateral triangle or to the highest point of construction, on the form resembling an inverted Literature T. Own weight makes the blank rushing down, thereby clearly denoting the vertical line. The device is applied to the base to the surface being checked. If Waterpas is not located exactly in the middle, i.e. Does not repeat the central axis, the surface cannot be recognized horizontal.,
All types of construction levels applied today in construction perform similar functions. Use them for marking designs before filling the screed, alignment and plaster walls, before mounting drywall and suspended ceilings. Markup and check devices are needed when the plumbing, window systems are produced.
According to the functional purpose, representatives of the construction level families are divided into two groups:
- Devices that serve to control. With their help check the quality of the masonry, the horizontality and verticality of the constructed surfaces, mounted systems, communications, devices. The control group includes bubble building levels, often referred to in honor of the immediate predecessors by Waterpas.
- Devices used for marking. With their help, the position of points is determined relative to horizontals with verticals, the contours of the created surfaces are drawn. The specified group includes the simplest water levels, plumbers, and a more complex and high-precision category - laser devices.
There is no universal construction level. For example, in the markup, the bubble type is a very weak assistant, although there are ruler with a millimeter scale on a number of models. Its appointment is to display deviations from horizontal. The working line is only one, the remaining three auxiliary: to apply them to any surfaces does not make sense.
Primitive plumbing can also be used for breakdown, and for control, but exclusively vertical lines. Place marking is best done with laser level. True, the cost makes think about the feasibility of acquiring an expensive instrument for a single work.
The antediluled water level is indispensable if you want to repel the point at one height in the rooms separated by partitions. Before buying these devices and devices, it is necessary to think carefully on the intensity of use and over the rationality of costs. You need to weigh that from the tools you need to purchase, but what is cheaper to rent.
In any case, you need to know exactly how to choose a building level, and clearly represent the scope of its use.
Bubble building levels
In the title of an uncomplicated control device, other than the "bubble" definition on equal bases, may appear "alcohol" or "oil". In the people, depending on the shape of the body, they are magnifying "boxes" or "rail". It is a timber or rail with mounted ampulus filled with mainly liquid, partially air.
The body is most often metallic, less often plastic, but there are still obsolete wooden options. Among the materials of the case in the priority metal, because The polymers are not sufficiently heavy and resistant to deformities, and wood products need elevated attention, regular testimony and scrupulous care.
Regardless of the name, the principle of operation of bubble levels is one. It is based on the difference in the specific gravity of the liquid and gas, as well as the inability of substances with a different aggregate state mix. Simply put, what position would not accept the construction level, the light air bubble would always be at the top of the vessel curved into the same side. If it is established exactly in the middle, it means that the surface is immaculately horizontal.
The volume of the bubble does not change, this prevents hermetically sealed ampoule flask. It will not disintegrated into several components, because the liquid will continually push the air up and group its scattered molecules into a single formation. To make sure, shake a tightly closed with a jar with water. The small bubbles that appear in it will soon disappear, and the distance between the lid and the surface of the liquid will remain the same.
Functional Classification
The number of mounted flasks determines the functionality of the construction level model, because devices:
- With one ampoule in the center of the work facing the search for deviations in the horizontal direction;
- With two ampoules: the central flask for controlling horizontals and side for checking vertical planes and lines;
- With three ampoules, two of which are intended to test verticals and horizontals by analogy, and the third is used to control inclined lines and planes.
The third variety with three control flasks is universal. However, if the level is purchased only in order to qualitatively draw a screed or, in the third control device there is no reasonable need. He is in demand mainly in the construction of roofs and in the device of stairs.
The sealed flask is filled with alcohol or oil solution, the freezing point is significantly lower than that of ordinary water. Therefore, working with a bubble building level was possible at negative temperatures. Solutions are tinted for the brightness of perception. They are distinguished by a smaller than that of water, fluidity, due to which air bubble in the flask moves with a sufficient sufficient for the calm visual fixation of its position.
Convenience and additions from manufacturers
The building level housing is a conventional rectangular or brazing section. The result of the testimony shape of the body does not affect, but it can be comfortable or uncomfortable for a particular human hand. The definition of the ergonomics of the device is purely personal, but before buying it, it is advisable to hold. For the dough on convenience, it is necessary to banally hold the tool in the hands, compare several options.
Among the options offered by manufacturers to facilitate work with the construction level:
- A magnifying lens allowing without voltage to read the instrument readings;
- Introduction to fluid fluorescent components to read indications with insufficient lighting;
- Rubberized hounds of the type of capture to improve ease of use;
- Magnetic inserts on the edge applied to the test surface, for fixing on metal structures;
- The rules that allow simultaneously checking verticals with horizontals to control geometric parameters.
Building level models are manufactured with listed additions and without. Nevertheless, the main convenience of the ampoules, pleasant brightness of the liquid and the clarity of the scale recognize the right.
Those who wish to buy a level with useful options, it is worth thinking about the possibility of their use. The price of the instrument, they will definitely increase. Is it reasonable to overpay for the fact that it is absolutely not necessary to solve already set or only planned tasks?
Accounting prospects
Retail control devices are available now and in electronic form, but the demand for ordinary bubbles did not fall at all. Easy bribes. After all, proven practice that the simpler the device, the most reliable and longer it serves the owner.
A simple device is easier to master, will not cause difficulty maintenance, it is almost never required to be redefined.
To perform various control operations, levels are released from 0.4 m to 2.5 m long. Depending on the brand, the scatter can be in both directions from the specified limits. Thinking over the question of which construction level of the bubble group is better to choose for household needs, it is necessary to focus on their own needs and real prospects.
It should be borne in mind that devices:
- Long from 2m and more are intended to control the planes of floors and walls, to test the quality of the screed, aligning plaster;
- 1 - 2m interval length are used to verify the evenness of brickwork, geometric data of suspended and stretch ceilings;
- The length in the 0.4 - 1m interval is suitable for the arrangement of window and doorways, for installation and hanging various household appliances, to perform various finishing and repair manipulations.
Do not forget that about the place of storage of the construction level with a length of over 2m must be taken in advance. Remember that the error in long devices is significantly less than that of short fellow.
Aspects deserving
The simplicity of the design is not in vain inspired falsification of muddy thoughts on the possibility of serial production of fakes. Checking documents for products before purchased will save from the offensive mistakes and from the purchase of "left" devices.
Products of domestic producers must comply with the GOST 9416-83 protocol, devices from foreign manufacturers - ISO 9001 Regulations.
In addition to checking technical documents, the buyer of the bubble construction level is necessary:
- Thoroughly examine the state of the main elements of the device - ampoules with liquid;
- Determine the size of the instruments and the color of the fluid;
- Inspect the fasteners. There are models on sale, whose flasks are fixed by adjusting screws. They need them or not - a controversial question. According to experts, levels should not be regulated independently. The result of the efforts of unstucking people is too dubious.
- Explore the clarity of the application of the metric scale and transport sections, if there is an ampoule to control the angular directions;
- Test ergonomics, i.e. hold in hand;
- Examine the condition of the hull.
- Check reading accuracy.
Most specialized stores have benches with an impeccable horizontal surface.
Suppose you buy a level in a recently open outlet point or online store. In such situations, the accuracy of the readings of the control device is checked as follows:
- We find a horizontal platform where the test level can be freely fit. Without instrumental definitions, it should seem almost smooth;
- Apply the tool to the surface. A marker or pencil outline the contour of the angles so that the level can be put on the same place again.
- Fix and remember the position of the bubble. We note how rejected by the risks.
- I turn over the level of 180º and install it according to previously made tags.
- Fix the position of the bubble. If he occupied a similar position, there was no doubt about the accuracy of the device. If not - check a couple more devices.
An ampoule responsible for verticals is checked by an identical method, but on the vertical plane. Even in the people there is a way to apply two Waterpasov to each other with working places. The position of the bubbles according to this method should be the same, otherwise one of the devices are brazenly lying.
There are also tips, according to which the horizontal line of the water level or laser level is fed to check the rush device, whose principle should also be studied.
The simplest water level
A device of two equal flasks interconnected by a flexible thin hose consists of a flexible thin hose. Used in the markup of horizontal lines, if the breakdown should be made in different rooms or at large distances. Those. Where the use of laser level is impossible, unprofitable or meaningless.
The principle of an elementary device is based on the law on reporting vessels. The water level in both communicating vessels will always be on one absolute mark, to fix which is risks on the flasks.
The use of water device allows you to correctly repel the horizontal regardless of the actual position of the floor surfaces, the ceiling, parapet, etc. No digital device has yet been able to replace it. Note that the reference horizon is beaten by the water level, from which after the indicated height project is postponed. With it, it does not produce direct marking of future planes formed by mounted ceiling, lags or, point of installation of plumbing devices, etc.
For marking water, we will invite an assistant, we will act like this:
- On the wall we mark an arbitrary point at a distance from the floor, convenient for the production of markup;
- Apply one of the flasks to the point, fix and remember, at what mark the water level was established;
- We send an assistant to the desired point. Moving your flask up / down along the wall, it must find a position in which the water level will be installed on the equivalent mark.
Good pluses of the device: low cost, simplest operation and accuracy. Cons: Lack of ability to break down at negative temperatures, limited application, the need to wait for the moment of setting the level in both flasks.
Advanced laser devices
Buy a laser level for use in domestic conditions consider it unprofitable. Why is it needed at all, if the markup can be carried out using a water level and a ruler? However, the owners who have decided to seriously equip country possessions, the laser instrument will surely come in handy. It will help to deal with open areas and closed rooms, will ensure the accuracy of vertical and horizontal lines, if necessary, will notice the entire planes in the processed space.
The construction uses a variety of models of laser devices: from compact pocket appliances with an elevated laser pointer to ultra-shaped multiprizmenny devices, allowing the markup in three mutually perpendicular planes.
The miniature option is ideal for everyday household needs and cosmetic repairs. To perform an in-depth redevelopment, cardinal alignment of surfaces, laying pipelines, it is desirable to get a serious laser level, installed in a stationary position on a tripod or on a wall bracket.
Most lasers used in the construction of only vertical and horizontal. Some new modifications are equipped with the function of breaking the inclined lines required during the construction of stairs, for example. Briefing on the use is easy, manufacturers are attached to the device a detailed description. The optimal color of the laser beam is considered green, because He does not annoy the eyes, and also perfectly read in a brightly lit room and on an open area in sunny weather.
Finally clarify the question will help videos with a detailed explanation, how to competently select the desired device.
Bubble variety devices review:
Checking the accuracy of the bubble level:
The analysis of compact laser levels:
Summarize. The construction level of the roll type with bubble "sensors" is not used for marking. With it, they check the horizon and verticals of the constructed and restored structures. The breakdown of the room and the construction site is performed by laser devices. If the laser is not available at the cost markup produce an old-kind plumb to a pair with a water level. There is no universal device, each of them performs its own functions.
