Everyone at least once, but always faced if not with the construction, then with the repair of any objects( premises).One of the stages of work is always the preparation of the foundation, and the list of measures includes leveling the surface. How much it is troublesome and difficult, it is not worth talking about.
But it's not even that. All kinds of plumb bobs, slats, weights and strings do not provide the required accuracy. And any error directly affects the quality of the work performed. The second drawback of using improvised tools is the complexity( and sometimes even impossibility) of using them in large areas or difficult to access areas. The laser level has no such drawbacks and allows you to make markup under any conditions.
A variety of similar products is the laser level self-leveling. What is its peculiarity? After preliminary alignment, all the settings are made automatically( hence the name).In principle, nothing complicated in the design of laser levels, but before buying a device, you should pay attention to a number of points.
Temperature application mode
Each model has its own characteristics. You need to focus on where the level is supposed to be used. Since everything can not be taken into account in advance, it is advisable to choose such a device so that it can be operated not only indoors, but also outside it, even in winter. If you really spend money, then the laser is advisable to buy for use in any situation.
Beam range
Again - for work on what areas is the device purchased? Limits range - from a few( 10 - 20) to hundreds( 250 - 300) meters. But the linear dimensions of land plots( whether it's a house or a summer residence), as a rule, do not exceed 40-50 meters. That's what we need to proceed from, since the higher the laser power, the more expensive it is.
Device type
Self-leveling models can be electronic or pendulum. The first have increased accuracy, but their price is higher. The pendulum also does not give significant errors, but after a certain time( about 20 minutes) they are disconnected, and they must be "put out" again, which is not always convenient. But they are much cheaper and for household purposes the is quite suitable. The most expensive models are of mixed type( manual control + automatic).But this is more for professional use.
Kind of label
Beam or dot. More universal models are ray models, since they allow you to make not only the marking of areas, but also the level tracing.
Rotational levels allow you to project, in addition to verticals and contours, also the plane at an angle. With them you can work even in bright lighting both in the house and on the street. But the price of such lasers is much higher.
Power supply
From mains, battery or "finger" type batteries? The latter option is preferable, because the batteries are inexpensive, and replace them - a minute. With the battery is more difficult, and not only because it will have to constantly recharge. Not all types of products are suitable for long-term storage( and yet the level in everyday life we do not use every day).We will also have to choose the appropriate battery, systematically monitor its condition. For irregular use of the laser level is quite troublesome.
Beam color
For some it is not important, but in daylight the green "thread" of the laser is seen better than the red one.
Alarm
In some models, if the installation is incorrect( deviation from the horizontal), the radiation is intermittent( beam blinking).
Tripod design
It is checked not only its serviceability, but also the correspondence of the mounting sockets to the mounting elements of the device( if a tripod is purchased separately).
Safety level
From the point of view of influence on the retina of the eye it is necessary to be guided by the models of the 2nd class.
There are a number of other parameters that characterize laser levels. But they are not of fundamental importance in the everyday use of the device. Among the manufacturers whose products are reliable and of high quality, you can put on the first positions such brands as "Bosch" , "Matrix" , "Condtro" , "Robotoolz RT" .Although on sale there are a number of other models that deserve no less attention.
Given the huge range of laser levels, you first need to determine the purpose for which the device is purchased and how often it will be used.
Price
It depends on the characteristics, and hence the capabilities of a particular model. The cost of protozoa starts from about 3 900 rubles.
«Bosch» ( seriesPCL) - production Germany. The simplest laser with a range of not more than 10 m;powered by batteries, self-leveling for deviations from the horizontal not more than 40.
Price - 4 180 rubles.
"ADA" - Chinese two-beam model with a sweep angle of 1000. Weight - 240 g, the presence of an audible alarm. The package includes a tripod, storage case, glasses and batteries.
The price is 6 850 rubles.
«CONDTROL» ( XLiner Combo series) - more powerful laser level. Range - up to 50 m, projection in 2 planes. The device includes 3 emitters, which makes it possible to use this model for carrying out works of almost any complexity.
The price is 13 655 rubles.
