Introducing the Ermenrich LT20 laser level: a versatile tool for construction, renovation and finishing work. It is fitted with split laser diodes that project two perpendicular lines. The leveller can be positioned up to 15 m from the surface onto which you wish to project the laser beams. The horizontal and vertical coverage reaches 130°. The compensator ensures that the two laser beams are perpendicular to each other. Given its extremely low measurement error, this tool helps you mark out areas of interest as accurately as possible.
The Ermenrich LT20 can be placed on a horizontal surface or mounted on a standard tripod. By using a tripod with a tilting head, it is possible to angle the levelling instrument to achieve the desired laser line configuration. This instrument is dust- and splash-resistant, a feature that is particularly important for use in the construction and renovation sectors. The laser level is powered by standard batteries. There are 10 brightness levels available.
