Horizontal Level bubble:
Select horizontal bubbles with different precisions according to requirements, and their precision is also called angle value. Note that for circular horizontal bubbles, the precision here refers to the inclination of the vial when the bubble moves 2 mm along any radial direction from the center of the differentiation line. For a long vial, the accuracy refers to the inclination of the vial when the bubble moves 2 mm along the axis of the vial.
The simplest is this type of horizontal bubble, which is simple in design, cheap in price, masters the observation method, and has acceptable accuracy.
A high-precision level can reach 4", and its length is 100mm, that is to say, when your level bubble moves 2mm, the error should be 0.002mm, the price is high, and it is suitable for high-precision environments.
