The spirit level is a measuring instrument that uses the principle of liquid level to directly display the angular displacement with a level bubble to measure the relative horizontal position, vertical position, and tilt position of the measured surface.

This level can be used for short-distance measurement as well as long-distance measurement. It also solves the shortcomings that the existing level can only measure in open areas and is difficult to measure in narrow places. It has accurate measurement, low cost, easy to carry, and economical. Be applicable.

The spirit level is mainly used to detect or measure the level and verticality. It can be divided into aluminum alloy square tube type, I-shaped, die-casting type, plastic type, special-shaped and other specifications; the length is from 10CM to 250CM and many specifications; The straightness of the material and the quality of the level bubble determine the accuracy and stability of the level.
