A rotating laser self-levelling is a great help for any kind of surveying work. Both professionals and do-it-yourselfers can survey any type of space with or without slopes.
The self-levelling function automatically adjusts the device so that the laser lines are aligned vertically or horizontally with precise accuracy. Rotating lasers with a locking function, on the other hand, are also able to measure slopes and inclinations.
High-quality rotating lasers with servo motors, on the other hand, are a special feature; they can measure “calibrated” inclinations with the help of the self-levelling function.
5 Best Self Leveling Rotary Laser Levels
What does a self-levelling function do?
Technical devices such as a rotating laser or cross-line laser offer professionals and do-it-yourselfers a variety of aids in the field of surveying technology. Surveying aids that are self-levelling are particularly practical. Because with the self-levelling function, it is very easy to create vertical and horizontal laser planes to within a few millimetres.
Complicated adjustments by hand and spirit level are no longer necessary, as the laser beam automatically aligns itself vertically and/or horizontally. The levelling accuracy indicates the deviation per metre. The lower this value, the more accurate the self-levelling of the rotating laser.
However, self-levelling can also be used to create calibrated angles. With the help of sensors, the device knows where the horizontal line is and calculates the angles on this basis. In this way, these devices are able to precisely measure a 3% slope. This is particularly necessary for large parking areas or similar.
However, only professional devices have such a calibrated, fully automatic slope function. Inexpensive alternatives rely on a so-called locking function. This can also be used to measure angles, but these are not “calibrated” and have to be set manually.

What are the differences in the self-levelling functions of rotating lasers?
A distinction must be made between horizontal and vertical self-levelling functions. However, it must be taken into account that not every self-levelling rotating laser projects vertical laser beams in addition to horizontal ones. Often only high-priced devices are able to perform horizontal and vertical surveys with the self-levelling function.
Only rotary lasers with fully automatic tilt functions make use of self-levelling when measuring angles and can thus create reproducible angles. How accurately rotary lasers with self-levelling work depends on the equipment and the price category.
The higher the quality of the device, the more accurate the levelling accuracy. This value is an important purchase criterion and ranges between 0.1 mm per metre and 0.05 mm per metre for most rotary lasers. With some devices, these values are also given as 1 mm/5 mm per 10 metres.
How does a self-levelling function work?
Most rotating lasers work with pendulum technology. Alternatively, there is the more sophisticated version with a servomotor. Pendulum technology relies on gravity to align the laser plane exactly horizontally. However, rotating lasers with a pendulum are not able to create self-levelling vertical laser planes. As a rule, only the higher-quality devices with servomotors can do this.
The additional function called the locking function is important. This enables cheaper models with a pendulum to create vertical laser planes. However, these must then be meticulously adjusted by hand, as the self-levelling function no longer works when the locking function is activated. Incidentally, the same applies to measuring angles with the help of a locking function.
Self-levelling rotary lasers with servomotors, however, work even more precisely and can generate horizontal and vertical laser planes self-levelling. With a fully automatic model, even exactly reproducible angles can be set automatically.
When does it make sense to deactivate the self-levelling function?
The self-levelling function cannot always be used. This is the case, for example, when a model with pendulum is used and slopes or vertical things are to be measured. But even fully automatic devices can reach their limits if the angles are too large and can only measure them with the help of the locking function. In both cases, the self-levelling function would be deactivated and you would have to set the desired angle meticulously with an angle plate or similar.
