GPR CIRCULAR PRISMS
The GPR range of prisms are supplied with a holder and target plate. The GPR121 Professional version is manufactured from quality metal components, for accuracy and long life. The GPR111, a low-cost Basic prism is moulded into a plastic holder and target plate.
MINI PRISMS
Conveniently storable in the instrument container, Mini Prisms offer a high positional accuracy due to their small size. The GMP101 and GMP111 have a built-in levelling bubble and supplied with an attachable spike. With this arrangement a point can be measured with very high precision.
MONITORING PRISMS
Suitable for permanent installations even in extreme environments.
The GPR112 has a patented air regulator to prevent condensation at the back of the prism. A rain shelter is available protecting the prism front against rain and snow.
The GMP104 Mini Prism is fixed in a metal housing, providing an extremely robust and precise monitoring target. Supplied with an L-bar for easy installation.
