A tribrach is a very important element that affects the accuracy of measurements. With its high accuracy, the tribrach was designed to work with most total stations.

Features:

The error in angle measurement is under 3 cc (60 Ncm torsion and 12 kg vertical load).
A centre line for each adjustment screw enables levelling the length of the screws. 
A 5/8" thread and a 8’ circular level vial.
The shortest focus distance is 0.35 m to 15 mln and an accuracy 0.5 mm/1.5 m.
Magnification 2x 
Working temperatures: from -20 ° C to + 50 ° C (-4 ° F do + 122 ° F)
