rules of use and what is it for? Types and models Any modern construction work involves some requirements for marking and therefore the usual tools (level, tape measure, level, etc. .) will not work.

Because with these tools it is not possible to get accurate measurements. For this reason, in order to obtain accurate measurement data, they began to use a laser level.

Next, we will talk about the different types of laser levels and how to properly use the laser level.

General information about laser levels

Of the total variety of levels, you choose the laser, and here it is very important to have that useful information, which will be discussed in this article.

Level types

There are three types of laser levels :

  1. Point (axis builders);
  2. Prismatic (line builders);
  3. Rotary (plane builders);

Rules for using the laser level

The dot-type laser level is two narrow beams. One beam is directed horizontally and the other vertically, so this tool is not suitable for decoration and construction work.

This laser level has a low price, low power consumption and long beam distance, so it is suitable for determining preliminary marking and determining the height difference between objects.

Very often, a point-type laser level is equipped with a rangefinder function - this makes the device more practical.

This level provides accurate data and therefore can be used for any finishing work, without using a plumb line or markup. For example, when gluing tiles , the solution is applied to the wall on which the markings are indicated, but the solution hides the drawn markings and the tiles have to be laid essentially at random.

The prism-type laser level allows you to see the markings over the mortar, which makes the laying of the tiles even and of high quality.

Rotational laser level is a plane builder and is a chiseled level that is installed in a rotating head.

Due to the high speed of movement, the point is transformed into a continuous line of the plane, which is located at a certain angle.

During DIY construction or repair work, rotary-type laser levels are not used, they are used only by professionals or designers.

Laser level device

Regardless of the type of laser level, it contains the following parts :

  1. Power supply;
  2. Emitting LED;
  3. Lens system that focuses the LED beam;
  4. Stabilization system;
  5. Shockproof and sealed housing;
  6. Remote control and control buttons.

The power source for the laser level is conventional batteries and rechargeable batteries.

The number of batteries or rechargeable batteries depends on many factors. For levels, diodes of red or green colors are most often used, the power of these diodes is from 1 mW to 1 watt. Usually, low-power diodes are always inserted in point devices, and powerful diodes are used in rotor levels.

But the diodes themselves are not capable of creating a point or a line, because they create a very wide beam of light and for this reason the laser levels are equipped with a lens system. The lens system and diodes are the most expensive components of the laser levels.

In order for the laser levels to work properly, they must be aligned and different systems are used for this.

Leveling systems

Mechanical alignment is done using a hinge, which is located on a stand - a tripod or small legs. In these devices, position adjustment is carried out, as with a conventional level, using a capsule with an air bubble. Tripod levels are easier to use when working, but cannot be used where the tripod does not fit.

Pendulum alignment.

Laser levels can thus be adjusted using a pendulum system, such systems independently set the level or level.

When the system has finished installing the device, a light or sound signal is emitted, which informs that it is possible to start work. Such devices are easy to use, but they cost significantly more, for this reason they are purchased by builders and finishers.


Laser levels are equipped with an impact-resistant and sealed case, this is necessary so that in the event of a drop or moisture on the device, it does not deteriorated. The power button on the device is needed to connect the LED to the battery or battery.

There are buttons on the device and on a separate control panel that are designed to select different modes of operation of the device. The control panel allows you to control the device from a distance, which greatly simplifies the work.

Selecting a laser level

Before buying a laser level, you need to understand what tasks the device will solve.

As a rule, the higher the characteristics and functionality of the device, the higher its price.

Inexpensive devices usually have low performance and are suitable only for finishing or installation work, in small areas.

Rotary laser level is suitable for finding out the boundaries of the marking, but where any materials will be laid on top of the lines, this type of level will not work.

The prismatic laser level has a high price, but it is also more functional, it is also used as an axis builder. Also, with its help, markings are performed on such surfaces, on which a solution or glue will be applied before laying the material. But a prismatic level is not suitable for creating non-straight lines; a rotary level will better cope with this task.

For DIY construction, inexpensive devices are suitable, and for more complex tasks it is better to use professional devices.

How to use the laser level?

  1. To use the laser level correctly, the level must be set in the correct place and if you operate the device on tripod, you need a platform of the appropriate size to install it.
  2. A level platform is required to set up a floor-standing or table-top unit, as these are more demanding than tripods. The deviation from the horizontal should not be more than twenty degrees, otherwise it will be difficult to set and fix the level and therefore there may be inaccuracies with the markings.
  3. It is best to set the level so that it points exactly to the markup, as this will reduce misalignment. After you have chosen the installation location, you need to level the device or the pendulum system will do it for you.

  4. When the device is ready for operation, it is turned on and dots, rays or crosshairs are set. Then check the levelness of the level.

It is necessary to set the level so that the vertical and horizontal lines pass strictly along the line installation of finishing or building materials.

When operating the device outdoors in sunny weather, it is best to use special glasses. Such glasses are often included with the device, but if they are not included in the set, then they can be bought at a hardware store.

Be very careful with the device that works as the laser beam can damage your eyesight.

In this text, we talked about the laser level and how to use the laser level and we really hope that this article was useful to you. We wish you good luck!
