The water level, which is familiar to many builders, is not always convenient for repairs, and besides such a device allows measuring only the horizon line. What can not be said about such a universal measuring device as a laser level, called in the building environment as a plane builder, a level by which it is possible to obtain more accurate, reliable and rapid measurements. How is the laser level, what is the principle of its operation, and at what points should I pay attention when choosing the device?

Laser level: device and scope
No construction can be built without precise measurements and maximum adjustment of the horizontal and vertical faces of the erected object. Among obsolete technologies, one can recall the use of laces, plumb bows and other devices for the exact construction of the foundation and the wall structures of the building. However, with the advent of a high-precision laser level, they were completely irrelevant, and can only be used as an additional technical solution in the construction sector.
Laser level is a compact, high-precision instrument made of dense plastic with rubber or latex inserts, protecting the device from the penetration of dust and dirt, which in abundance can be found on any construction site. The operation of the mechanism is based on the action of diodes that contribute to the formation of high-power light radiation, due to which the performer can perform a set of measurements of high accuracy, calculate the slope of the object not only in the construction field, but also in production, military affairs and other spheres of life.
Since the laser level is considered an innovation, it is better to familiarize yourself with user feedback, selection criteria and instructions for using such a universal instrument before acquiring it.
Advantages of laser level
Among the many advantages of measuring equipment, the following points will be noted:
1. Wide range of applications, assuming unlimited possibilities of using the level on open areas and in rooms on any surface for the best solution of a wide range of domestic and professional tasks: creating accurate projections in the horizontal and vertical, projecting the axis of coordinates in the form of a cross or a point that pierces the surface of the ceiling and floor by analogy with the action of the plumb. Some of the modernized instruments allow creating an accurate beam projection with coverage of almost the entire room and 360 ° turn angle. We can say that such models have unlimited possibilities of use.
2. High speed of measurement, allowing at least two times to reduce the time of work on marking ceilings and other surfaces. This completely eliminates dragging the water level pipe, moving from corner to corner, then again changing the location, pulling this time the shoelaces horizontally. The application of the laser level implies the execution of a sequence of simple actions: roulette should be repelled from the projection of the beam, make a marking after 0.5 meters and make the installation. Similarly, the vertical markup is performed.
3. High accuracy of measurements and constructions. Marking, performed exclusively on the ray, bypassing the use of roulette, is characterized by absolute accuracy. The use of hydraulics will not provide accurate results, since the human factor is not excluded, for example, the hand of the performer who has trembled at the most inopportune moment.
The only drawback of the laser level, judging by the feedback of users, is its high price, which can reach $ 1000.
We choose the best level: types of measuring instruments and their functions
Today, in the construction market, you can find the widest assortment of control and measuring equipment with different functional load, design and technological features, different price category and manufacturers-Bosch, Skil, Dewalt, Ada and others.
When choosing a laser level, first of all pay attention to the features of its design.Levels can have:
1. A simple construction, which is a lumbar level with a special laser mechanism. At a modest price, this level is limited in functionality, working with it is rather laborious, and for large-scale repairs it is not suitable.
2. More complex construction, equipped with an additional unique possibility of self-leveling. Such a device, resembling a cross that looks like it, occupies the necessary positions vertically and horizontally, and therefore does not need a rack-and-pinion level. Since the device is mounted on a wall, the possibility of using a laser level of this type when working with a floor surface is rather limited. The cost of such measuring equipment usually does not exceed $ 200.
3. Professional model, otherwise known as a laser level, has unlimited possibilities. Scope of application - small household and large-scale construction work.
The cost of home appliances fluctuates at the level of 200-300 dollars, but the professional model is estimated to be an order of magnitude higher - from $ 500 to $ 1000. The work of such devices involves the use of a tripod to successfully realize the possibility of circular beam projection. Wide functionality includes projection of a horizontal and vertical beam, a cross, points, projection of a straight line and an inclined line at different angles.
Distinguish between the pendulum and electronic laser level
Pendulum models They are equipped with a special pendulum with diodes placed on it which radiate a powerful light flux. It is the pendulum that serves to maximize the exact alignment of the horizontal with the vertical. The technological feature of the device allows you to simultaneously produce up to 5 measurements in a variety of planes.
The electronic laser level, which is a more complex design, is used for professional measurement work without the slightest errors and at great distances. The measuring device is equipped with a complex mechanism with a large number of tilt sensors, which work begins when the device is turned on.
In addition to the above models, you can find a measuring device mixed type, which combines various equalization mechanisms - manual, pendulum and electronic.
Note the type of beam designation:
point models, used on the surface and projecting onto the surface only a point;
linear devices, reflecting horizontal and vertical lines. Their purpose is to build planes;
rotational Levels with a complex internal mechanism and high speed of rotation of the LEDs. The use of such high-precision instruments provides the highest class of plane builders, which can simultaneously project several parallel beams at any height at any one time. This feature allows you to perform installation on the projection of the beam, bypassing the application of preliminary marking. The cost of the rotation level reaches 1000 dollars.
As you understand, such an expensive and difficult to use laser level is unlikely to be needed in an apartment.
And, finally, we note that it is difficult to talk about how to choose the best laser level, without any idea of the principles of its operation. Information of this kind you can learn from the video on youtube.
