Description
The Leica GPR112 is a large diameter monitoring prism ideal for long range measurements.
It can be installed on M8 or 5/8″ threaded bolts and it’s usually paired with a GHT112 Mounting Kit.
The Leica GPR112 has a built-in filter that prevents condensation on the reflecting surface and can also be used with a GDZ112 rain & snow cover. With this cover the prism is usable in poor weather conditions, even without regular cleaning.
GPR112 prism from Leica Geosystems was developed in response to customer demands in these specific market segments. The Leica GPR112 Monitoring and Mining Prism can be aligned in one or two axes to the instrument position, depending on the application.
The rotational axes intersect at the prism’s optical centre. All GHTI 12 screws are self-securing, therefore maintenance-free.
Features — GPR112 Monitoring and Mining Prism
- Large, uncoated prism, approx. 60mm visible diameter for long-range
- During temperature changes, brief condensation may occur at the back of the prism. The built-in filter guarantees a short drying period.
- Full ATR range for TPS1OOO and TPS1100 family instruments.
- Possibility for mounting on M8 stud anchors or threaded bars, e.g. as used in the HILTI DX (Direct Fixing) system, for ultimate ease of installation.
- Mounting-compatible with competing systems – 5/8″ adapter included as standard.
