Ermenrich LN20 laser level. The Ermenrich LN20 is a self-levelling laser level that produces four lines in green colour in the horizontal plane. Horizontal swivelling range - full 360°. The instrument is ideal for use in construction and renovation work as well as for the installation of appliances and lighting. The long working distance allows you to cover a large radius without having to move the tool - it can even reach a far wall. A compensator reduces vibrations and automatically aligns the laser level. The integrated lithium battery of the Ermenrich LN20 laser level ensures a long battery life, which depends on the selected brightness level (four options available). Even at maximum brightness, the LEDs last up to 8 hours, which means you do not need to charge the laser level during the entire work shift. The laser level is shockproof, dustproof and splashproof. It can be mounted on tripods using the standard 1/4 inch thread, which is very practical.
