The level is an indispensable tool when performing construction and installation work. It is necessary for the correct installation of doors, windows, laying bricks and tiles, checking the verticality of walls and horizontality of floors. With its help, modern household appliances and communications are installed.
The correct choice of measuring tool significantly improves the quality of work and saves time. By design, there are five main types of building levels: bubble, electronic, pipe, hydraulic, laser. Below we will look at each of them in more detail.
Which building level is better to buy?
There are six types of such devices on the market:
- Bubble or magnetic levels are optimal for home use. They are used to install windows or lay tiles.
- Thanks to their advanced functionality, electronic ones are suitable for serious home repairs and construction sites.
- Digital inclinometers provide highly accurate measurements and display them on a display.
- Pipe levels are used to level gas or water pipes.
- Hydraulic levels are used for floor screeding, when installing suspended ceilings and installing reinforced concrete blocks.
- Laser is chosen for larger scale construction work. They will help in marking walls, structuring the floor, conducting communications, etc.
Professional builders often prefer foreign brands such as Stabila, Matrix, Kapro or Stanley. But for those who want to save money, reliable domestic manufacturers are quite suitable, for example, a leading supplier of tools.

Best bubble levels
Bubble levels are popular because of their simplicity and low price. The air bubble in special flasks is a sensitive and quite precise element. When it is in the central part of the ampoule, the surface is considered smooth.
If you go to the side, there is a slope. There are usually three ampoules: for horizontal and vertical directions, as well as at an angle of 45 degrees. The measurement error of such an instrument is 0.5-1 mm/m. The length of the levels can range from a few centimeters to 4 meters.

How to check a tool
How to check the construction bubble level? Ask if the building materials store has a special stand for checking levels? If not, you will have to check on a horizontal plane. You need to place the device on the surface and press firmly. It is important that there is no gap between the level and the support. Carefully remember where the air bubble is located.
On a note! The buyer has the right to request a level check for measurement accuracy.
Now you need to turn the device 180 degrees, wait a little and check the location of the bubble. The previous and new positions of the air bubble must match. If this does not happen, then the device is defective.

- CLASSIFIER of building levels of all types and sizes. (The parameter selection form will open)
Construction levels are familiar to almost everyone today. They are widely used both in everyday life (adjustment, installation of furniture and household appliances, etc.) and in professional construction to check the horizontal and vertical position of building structures, floor screeds, plastering works, as well as to transfer the angle of inclination of structural parts to similar ones. details during construction and installation work. In general, in everyday life and at a construction site, there is nowhere without levels. However, not everyone knows, even professionals, that there are construction levels: for household purposes and levels that relate to measuring instruments and are produced in accordance with the requirements of GOST 9416-83 “Construction levels.
Technical conditions". How can you differentiate them and what is the point? So, construction levels that meet the above standard are produced in the 1st, 2nd and 3rd accuracy groups. This is an I-beam or rectangular profile of aluminum alloy GOST 2685-75, which has ampoules for measuring inclination angles. The 1st accuracy group has an ampoule division price of 2; 4; 6/ (minutes), i.e. 0.6; 1.2; 1.8 mm/m respectively. 2nd group – 15/, i.e. 4.4 mm/m. 3rd group – 30/ i.e. 8.7 mm/m. A distinctive feature of these levels is that the ampoule does not have two marks like household levels (Fig. 1), but more than two divisions in each direction (scale), which makes it possible to determine the deviation of the angle of inclination taking into account the division price (Fig. 2).
For a more convenient choice from the catalog of building levels and rules of all types and sizes, a CLASSIFIER of building levels is provided. Everything is clear, without confusion.

On the body of such a device there must be
: GOST number, division price of the ampoule and the name of the manufacturer or its trademark. In accordance with the requirements of the law “On Ensuring the Uniformity of Measurements,” these levels are subject to verification or calibration, since the work performed with their help falls within the scope of legal metrology. The cost of such levels is low, as is their verification. They have one, but very significant drawback: despite the length and accuracy groups specified in GOST 9416-83, in the CIS no one produces levels longer than 500 mm and levels of 1st degree. accuracy. Thus, only levels of the following types are available for sale in the CIS: US5-2-II (L=500 mm, accuracy group 2), US5-1-II (L=300 mm, accuracy group 2), US2-II ( L=300 mm, accuracy group 2). All of them have an ampoule division price of 15/, i.e. 4.4 mm/m.
Based on this, for certification and licensing of construction work in Belarus, electronic building levels from different manufacturers (Stabila, Nedo, Geo-Fennel, etc.) began to be used as levels of the 1st accuracy group, which meet the requirements of the levels of the 1st accuracy group, those. have a division value of 1mm/m = 0.1% = 3.3/. The document confirming the passage of metrological control for them is a calibration certificate issued by BelGIM or another accredited laboratory entitled to do so.
All other levels that do not meet the above requirements are classified as household levels (construction household levels). “Some” also call them control slats with a level, but in fact they are the same thing. The only difference is that BelGIM, if necessary, issues a CERTIFICATE for them as testing equipment, which indicates the deviation from the straightness of the working surface in millimeters over the total length. The ampoule at such levels usually has two lines (risks). Therefore, it is not possible to determine the angle of inclination of the surface. We can only state that the surface is deviated from the zero position, but by how much is unknown. And any requirements have acceptable values. In addition, the ampoule at such levels is very rough, its sensitivity is more than 30/ (8.7 mm/m). This means that if we raise the edge of the level by a few millimeters, we will not notice a displacement of the ampoule bubble. This is precisely what determines the everyday purpose of such levels.
