1) depending on laser and atmospheric conditions
2) typical high quality laser, 1m to 50m, 0° angle of incidence, numeric readout within -20mm to +50mm
3) MTR-90RF supports the classic Metor mRF protocol, which assures full compatibility
with MTR-125RF and its radio hard- and software accessoires.
MTR-90RF is compatible with Bluetooth Smart Ready® smartphones and tablets
using Android™ 4.3 or later.
4) 2m above ground, outdoors
