Leica GDF312

LEICA GDF312 — TRIBRACHS WITH OPTICAL PLUMMETSimilarly 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 centering. 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.The hysteresis of the Professional 3000 Series tribrachs amounts to a maximum of 3" (1.0 mgon). The foot screws are maintenance-free and have a larger diameter. This allows for fine adjustments, even when wearing work gloves under difficult environmental conditions. These tribrachs are suitable for non-motorized TPS instruments with angle accuracy from 5" to 7" and GNSS antenna stations as well as backsights and controlThe tribrach and optical plummet are of robust construction and suitable for long period exposure in all environments. These makes the GDF312 ideal for GNSS and backsights and control points.Specifications and data shown are subject to change with or without prior notice.
