3 Overview

Level is the level of the line of sight of the instrument as a baseline measurement of height measuring instruments performed. It is widely used In geodetic leveling, crustal deformation measurements, and a large variety of engineering leveling precision machinery installation. Press sensitive member Divided into vial spirit level, automatic Anping Level. Level different Anping divided into three accuracy level Gender. vial spirit level DS05 level, DS1 level, DS3 level and Automatic Level DSZ05 level, DSZ1 Level, DSZ3 level.
