The automatic plumb laser LL-91L with green laser beam is a laser for plumbing up in laser class 3R, capable of electronic self-levelling over two axes. OIur new green laser beam noticeably enhances visibility of the target, even in difficult lighting conditions. This is because the human eye is four times more receptive to green light than to red. In addition, green light does not get overpowered so much by the red spectrum of the sunlight.
Every time where there is the need to project a point exactly vertically up, this laser is the right choice.
This laser is also available with a higher precision of ± 2,5 mm/100 m and alternatively as LL-90L in laser class 2.
