The Ermenrich PRO LV20 laser level makes 6-line markings. The device forms a plane horizontally with 360° scanning, and creates two lines vertically. The green laser beam is clearly visible at any light level. The brightness of the lines can be manually selected from 4 levels. Adjusting the brightness helps to adjust the visibility of the lines to the lighting conditions. It also affects the operating time of the device: at maximum brightness, the leveler can operate for 6 hours, and at minimum brightness, 35 hours.

The compensator in the leveler monitors the tilt level and indicates when the device needs to be adjusted. This is how the automatic leveling mode works: if the device tilts more than 4°, the laser starts flashing. The leveler can be switched to tilt mode by locking the compensator. When building stairs or creating more complex home decorations, you may need to create a sloping/rising line.

The 30-meter working range of the leveler is ideal for both home and professional tasks. The range can be further increased with a laser receiver (sold separately). The leveler works with it in pulse mode.

The device is protected against water spray and dust particles, so it can be used without interruption even on large construction sites. The leveler has an impact-resistant design. As a result, it remains intact even in the event of an accidental drop. The device is powered by a rechargeable battery that can be charged using a USB Type-C cable. The set includes an L-shaped magnetic bracket, the distance of which can be adjusted from the wall.
