The spirit level is a commonly used measuring tool for small angles.

A spirit level is a commonly used measuring tool for small angles. It is mainly used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the guide

rails of machine tool equipment, the horizontal and vertical positions of equipment installation, etc.

There are many types of spirit levels. Common ones include bubble spirit levels and electronic spirit levels. The bubble spirit level uses bubbles in the liquid to indicate the horizontal position.

It has a simple structure, is convenient to use, but has relatively low accuracy. The electronic spirit level uses electronic sensors to measure the angle. It has high accuracy, intuitive display, and

some also have data storage and transmission functions.

When using a spirit level, it needs to be placed on a stable surface, and then observe the bubbles or digital display in the spirit level to determine whether the measured object is in a horizontal

state. If higher accuracy is required, multiple spirit levels can be used for measurement, or more advanced measuring equipment can be used for calibration.

The spirit level is widely used in fields such as construction, mechanical manufacturing, decoration, etc. It is one of the important tools to ensure the engineering quality and the accuracy of

equipment installation.
