Soja b-series auto-equilibrator to measure reliability under all environmental conditions。
Optimally designed telescopes provide bright and clear images and help to reduce the eye fatigue of surveyors; 20 cm short-sightedness (from the front end of the telescope) allows them to remain accessible in a narrow, closed space environment. Crude double-speed chars substantially increase the operational speed of the instrument (b20)。
Horizontal angle measurements directly read the angle reading of 1 radium. Horizontal palettes can be set when sampled or lined, and reading windows on the seat directly below the mirror make horizontal angles easier to read。
Even when operating on slopes or large ups and downs, round tripods make it easier for the instrument to be installed and can also be used on flat tripods. Through a prism or a plane mirror next to a telescope
