The accuracy of bubble level is usually high and can meet general measurement needs. Although its accuracy may be affected by bubble size and observer judgment ability, through reasonable design and use, relatively accurate measurement results can still be obtained. The bubble level has good stability during the measurement process and is not easily affected by external factors. This enables it to maintain high reliability even in situations where high-precision measurements are required.

The use of a bubble level is very simple. Simply place it on the plane to be measured and observe the position of the bubble to determine its levelness. This intuitive operation method allows users to get started without complex training. Bubble level is suitable for different occasions and industries, such as construction, home decoration, mechanical manufacturing, etc. In various scenarios where horizontal measurement is required, bubble level can play an important role.
