Leica GDF101 Tribrach Without Plummet Black for Light Weight Survey Instrument
Model: GDF101
Highlights:
Introduction:
The hysteresis of the Professional 1000 Series tribrachs amounts to a maximum of 5" (1.5 mgon). The GDF101 and GDF102 are cost effective tribrachs which prove themselves in use under normal environmental conditions. These tribrachs are suitable for non-motorised TPS instruments with angle accuracy of 7" and single frequency GNSS antenna stations.
Leica Tribrach
Similarly to the stability of the tripod, that of the tribrach is a significant factor in measurement accuracy. The torsional rigidity, the most important criterion of a tribrach, is constantly controlled and tested during its production. The maintenance-free foot screws of the Leica Geosystems tribrach provide movement that is always smooth and free of play, even after years of use. The precise alignment of the support area to the base plate of the instrument assures extremely accurate forced centring. The optical plummet is so robust that the need for adjustment during the entire lifetime of the tribrach is practically unnecessary. Its construction predestines the tribrach for all applications, including extreme temperatures and high dust and humidity.
