TOP 20 best laser levels: 2021 rating by price/quality and which self-leveling one to choose for home

For installation, construction and repair work, a laser level is indispensable. It is used to construct horizontal and vertical landmarks.

The modern range offers models for both beginners and professionals. But how to choose a reliable device among all the abundance of models? What should you pay attention to?

What characteristics should a quality tool meet?

We studied the most popular models and, based on their technical parameters, customer and expert reviews, compiled a rating of the best laser levels in terms of price/quality ratio, which you can safely buy for rare or regular use.

Rating of the TOP 20 best laser levels of 2020-2021

How to choose a laser level for your home?

To choose a reliable device that will last a long time, take into account the following points::

1. Error . No more than 0.5 mm, and preferably within 0.2-0.3 mm.
2. Radius of action . 15-20 meters is enough for a room; if necessary, you can use a receiver.
3. Management . It should be simple and understandable. It is very convenient to use devices controlled via a smartphone.
4. Tool protection . The level should have rubber inserts that will protect the device from falls.
5. Equipment . Determines how convenient it will be to use the device. The case is needed for storage and transportation. Various mounts and brackets allow you to save both money and time, since you do not have to deal with the separate selection of accessories. Glasses improve the visibility of the rays.

There are no fundamental differences

Both the level and the level build laser planes designed for precise work. The first term, as a rule, refers to entry-level devices that have a simple design and are the most affordable. Simple intuitive operation and small dimensions allow the devices to be used in everyday life.

Laser levels, as a rule, are called professional-class equipment - complex, relatively expensive and maximally functional. In most cases, it is used on construction sites.

What is the operating principle of a rotational laser builder?

The price of laser rotary levels is always high, however, this device has a simple operating principle. The operation of the measuring level is based on the construction of a plane due to the glow of a bright LED. The rotary level received this name due to the construction of a 360-degree horizontal plane.

With a rotary device, you can build a horizontal plane over the entire area of ​​the room, which is an immediate advantage. The ability to construct a plane along the entire perimeter of the room is achieved by moving the beam by rotating it. This is achieved through the use of an electric motor, which drives the laser beam. Depending on the place of application, the devices can be street or geodetic and construction. They differ not only in cost, but also in the degree of protection from dust and moisture. While a geodetic level can be used for measurements indoors, measurements cannot be taken outside with a construction tool for interior work. This is due to the following reasons:

• A low degree of protection will lead to the ingress of dust and moisture leading to rapid failure of the tool.
• Inability to detect projection due to low beam illumination
• Low projection range, which does not exceed 20 meters

The rotary device has not only a horizontal plane construction, but also a vertical one in the form of a point. However, this option is not available on all models of laser levels. To construct a vertical plane, the same laser beam is used, only for this purpose the device is installed on the side wall.

This is interesting!
The further the level is able to project the plane, the higher the error rates.

What is a level?

A level is a geodetic instrument that allows you to measure the difference in height of several points. This device is widely used in construction work that requires accurate measurements. The presented level can be used to record terrain features, as well as to apply markings and monitor the compliance of an already built room with established standards.

According to their design, these measuring instruments are divided into three groups:

• optical. They have the most optimal price-quality ratio;
• electronic. Equipped with a data storage function. Have a minimum measurement time;
• laser Among their analogues they have the highest measurement accuracy.

A rotary level is classified as a laser instrument.

Operating principle

The principle of operation of the rotational level is based on the projection of a laser plane due to the constant rotation of the LED. The movement is carried out by a built-in electric motor. Due to the design features (in other laser instruments the beam passes through a prism), the measuring range of the device is significantly increased. Some devices are capable of taking measurements at a distance of 1 kilometer.

How to use a rotary level? Before you begin taking measurements, you must install the tool correctly. To do this, use an ordinary bubble level built into the body of the device (if it is not equipped with an automatic leveling function). The instrument is mounted on a flat surface or a special tripod called a trigger. After this, it is necessary to slightly change its position until the bubble in the level reaches the desired location. If the device is equipped with self-leveling, you can start taking measurements immediately after installing it.

How to check a tool

How to check the construction bubble level? Ask if the building materials store has a special stand for checking levels? If not, you will have to check on a horizontal plane. You need to place the device on the surface and press firmly. It is important that there is no gap between the level and the support. Carefully remember where the air bubble is located.

On a note! The buyer has the right to request a level check for measurement accuracy.

Now you need to turn the device 180 degrees, wait a little and check the location of the bubble. The previous and new positions of the air bubble must match. If this does not happen, then the device is defective.

Which company should you choose?

Main types

To choose the right laser level, you need to know about the existing types of these devices. Manufacturers offer:

• linear levels (so-called crossliners). A larger or smaller plane is formed, the size of which depends on the scanning angle of the device. They form a line only in the direction in which they are turned. Crossliners are well suited for simple construction and finishing work;
• rotary levels. Thanks to the special system that is implemented in them, they produce laser planes turned º. The same system leads to a significant increase in the cost of rotary levels in comparison with linear models. They have a long range, much greater than that provided by crossliners. Such devices are most often used on construction sites.
