How to choose a laser level - the main secrets of successful purchase

Types of laser levels

leveler - is a tool for determining the difference in elevation between the different points of the surface.Initially the level used in geodesy, he measured the height of the terrain.Today it is the most demanded tool in the construction of which is capable of projecting a laser beam to an object in the form of dots or lines.

All devices use the principle of rotation of the laser beam.With the help of the device can be aligned in two planes, markup, measure distance, perform work at different angles, or use it as a plumb line.The choice of laser leveling is possible between the two types: prismatic and rotary.Let us examine what the best laser level.

comparing laser levels shows that the more reliable is considered a prism unit.As there are no moving parts, the light is converted to a prism in two perpendicular intersecting plane scanning angle turns around 120 degrees.This device is sufficient for most tasks of construction.

Rotary level has great compared to the prismatic features.He has a large range, with some models up to one kilometer, and the scanning angle of 360 degrees allows you to capture the entire space.This device align door and window openings, narrow walls and other hard to reach places.

Function Lasers - pay attention when buying

How to choose a laser level, depending on the intended scope and the work place.The first thing you need to pay attention - what a plane can build the device.The best option - 3 plane, two vertical and one horizontal.In most cases, two perpendicular lines.

second point - the type of leveling leveling.There are 2 types: manual and self-leveling.Which laser level is better?When manually use the built-in bubble level, self-regulation is more convenient.Self-leveling range of about 4 degrees, the instrument itself reaches the maximum level position.

The greater the angle of self-regulation, the easier-to-use level.Self-leveling function can be switched off if the instrument is deliberately need to put a certain angle.

test laser levels shows that signals self-leveling abuse are different: some devices are turned off, the other light flashing lines, and others publish a special sound, there are variants of the combined warning.

important presence Failure warnings.In the process, there is always a chance that the level may be shifted.Once this occurs, the instrument starts to beep - flashing lines or sound.Note the Sleep function.In general, levels powered by batteries, and this function is required to store a charge therein.After a period of dormancy level is automatically switched off.

maximum range of building planes - a measure of how far can stand on level surface, with which the work.The presence greatly increases the range of the receiver.Very nice to have feature lines off - if you need one line, and the rest can be turned off.It saves battery and work much more convenient when the second line is not obstructed.

What you need to remember is already in the store?

Before you buy look no thread, which the device is attached to a tripod.The most common - 1/4 and 1/8 inch, but there are also other sizes - 8.5, for example.There are devices with two thread types, they can be mounted on any tripod.A typical question for the seller is: "Advise laser level."But at the same time you need to know about what he would say, at least the terminology.That's why we brought the most complete description of the most important properties of leveling up.

accuracy of construction - an important characteristic leveling, which shows to what maximum value can deviate from the horizontal beam. The higher the accuracy, the better the quality of work.We need to look, the device works with batteries or battery.In the battery device works longer, but if it fails, will have to spend money.

The label indicates the laser class.Safe class is not higher than the second, in either case you need to buy glasses to protect your eyes from the burn.Color beam principle does not matter.The beam can be red or green, green, pleasant, but there is such a device is more expensive.
