Construction laser

topoMAT IPX5

Needs no more than one person to take care of levelling jobs: Efficient, automatic and safe in all situations. A universal levelling system for various jobs. The electronic inclination measure allows fast measuring of inclinations between 0 and 90 degrees. The angle measure is detachable and can be used solo. The topoMAT is also available without the inclinometer.

Precision and safety
  • As a result of the automatic self-levelling function with an accuracy of ± 2.6 mm/30 m
  • ESP - automatic laserstop function in case of impact or other changes of position!

LASER operating modes
  • Rotation – with 600, 300 and 100 rotations per minute – to choose the optimum task-suited rotation speed!
  • Line-mode – with settings of 15, 30, or 45 degrees – to create visible laser lines or different lengths especially inside buildings!
  • Dot-line mode – to the right or left – optional for the slow or fast retracing of laser dots or laser lines – function can be enabled directly at the laser or via remote control!
  • Permanent angle through the firmly connected beam splitting prism.

No time-consuming modification
Fast variable changing from horizontal to vertical operation with lockable 90° tilting joint.
