899 Prolaser® Electronic Rota-Line



The 899 Prolaser® Electronic Rota-Line is built with advanced electronic laser technology and designed for both indoor and outdoor leveling. The 899 projects a laser dot which rotates at high speed to generate a bright and clear 360° line that can be projected horizontally or vertically.


It is electronically self-leveling up to ±5° in both the X and Y planes, has a manual leveling option for setting slopes and an automatic shut down function when out of level. It boasts an exceptionally high accuracy of 0.0001″/″ (0.1mm/m) and an indoor range of up to 165′ (50m) and outdoor range of up to 500′ (150m) with the laser detector.


The laser has 5 adjustable rotation speeds and 6 scan modes to create visible laser lines. The laser detector has both visual and audible signals and can be easily mounted using the detector clamp (included).


The 899 comes in a durable, rainproof casing to protect it in the tough outdoor worksite conditions.
