3 Overview
The frame type and strip level are based on the principle of liquid level, and the horizontal displacement is directly displayed by the level bubble, and the measurement is relative to
A universal angle measuring instrument with a slight tilt angle for horizontal and vertical positions; it can also be used to measure various machine tool guides
Straightness, flatness and parallelism, correcting the level of installation and vertical position of the equipment.
The outline structure of the frame level and the strip level is shown in Figure 1 and Figure 2.
