On large sites every metre of working radius counts, and so does every minute not spent hunting for the laser plane. The MTR-90R covers a 400 m radius around the laser, captures the plane over a 90 mm capture height and shows the deviation numerically with a linearity error below 0.5 mm.
Key benefits
- Working radius up to 400 m with a class 2 laser, one instrument position serves wide construction fields.
- Capture height of 90 mm, asymmetric from -30 mm to +60 mm, the capture field sits where the rod is normally placed.
- Numeric readout with a linearity error below 0.5 mm and deadband settings from 0.1 mm to 20 mm, the receiver adapts from fine levelling to rough excavation.
- A single AA cell lasts more than 45 hours, that is one battery change instead of two and a spare every site container carries.
- Reception angle typically ±70 degrees, the receiver does not have to be aimed precisely at the laser.
- IP67 protection and a rubber overmould, plus 36 months warranty and manufacturing in Germany.
- Audio signal at typically 100 dBA on the high setting, audible next to running plant.

Applications
Excavation, formation level and slope control in earthworks and civil engineering, road and pipeline construction, foundations and formwork, plus height transfer in structural work. The large working radius and the asymmetric capture height pay off when the laser stands far away and the rod is moved often.
Compatibility and scope of delivery
The MTR-90R is the Metor MTR-90R built in Germany by AndroTec GmbH and listed by Leica Geosystems under material number 960234. It works with all common red and infrared rotating lasers. Green rotating lasers are not detected. Delivery includes:
