Today, you can find a variety of constructionlevels, but the most reliable and precise on the right is a laser level. But before you buy this miracle of technology, you need to understand what are the laser levels, their characteristics and possibilities, and only then make a decision to purchase any model.
Laser levels are: rotary and prismatic
The design of several layers of prismaticLEDs, their light is created by a special prism. As a rule, there are two that creates two beams - vertical and horizontal, forming together a cross. In most cases, all the models of these levels make it possible to disable / enable each beam individually as needed. The range of the beam of these levels is relatively small, but these laser level perfect host, to do work in the house.
Rotary levels - they are more suitable forlarge-scale construction projects. Their operating principle is based on the projection of light using LEDs with a large rotation speed, the range of the level reaches about 500m.
In rotary leveling, before the positional theremany advantages. With the help of, for example, can easily draw a circle sector and align the doorway. These levels also show the scanned light beams - are segments on the surface, varying in thickness.
Typically, rotary selected levelsprofessionals, their price is several times more than the cost of the prism levels. That is the preferred prism greater levels naturally, if you are not a builder professional.
There are also point levels of visible ray, they provide only a point on the reflective surface.
Alignment light beam
This is one of the most important points at the beginning of the level. The beams can be aligned automatically or manually.
Laser level manually aligned the bubble, it is usually built into the enclosure. This method of alignment should be set aside some time and effort.
Self-leveling pendulum level hasset design pendulum, he, with the inclusion of its own weight levels LEDs so that clearly reconciled vertical and horizontal. These Levels themselves off after 20 minutes of work. These levels can create up to five simultaneous beams in different planes, that the measurements to minimize the likelihood of error.
Self-leveling electronic levels consideredthe most accurate and sophisticated. These Levels hardly produce errors even at great distances, and immediately ready for operation. Electronic precision levels have a complex mechanism with tilt sensors.
Lasers have a mixed type of electronic mechanisms, pendulum and manual alignment.
Advantages and disadvantages of laser levels
Current levels have many benefits, we select just a few:
• Accuracy of measurements. If the marking is done only by the beam, construction and measurements are the most accurate. Eliminated in the human factor, which takes place at the hydraulic level measurement.
• High speed. marking measurement, for example, drywall construction can be made twice as fast.
• Large range of applications. The most elementary levels provide projections on the horizontal and vertical directions. Features "clever" almost limitless leveling in construction work.
Perhaps the only drawback, which haslaser levels, is their cost. Price varies within wide limits, so try to trim a laser level, depending on what kind of problem you need to solve. Since the cost of laser level, the ability to do multi-function operation, can be up to $ 1,000.
