Digital display vernier caliper

Mechanical vernier caliper

The vernier caliper is a gauge for measuring length, internal and external diameter and depth. The vernier caliper consists of two parts: the main ruler and the sliding vernier attached to the main ruler. The main ruler is generally in millimeters, and there are 10,20 or 50 divisions on the vernier. 

 

According to the different divisions, vernier caliper can be divided into tenths vernier calipers, twenty degrees vernier calipers, fifty degrees vernier calipers, etc. The vernier is 9mm for 10 divisions, 19mm for 20 divisions, and 49mm for 50 divisions. There are two pairs of movable measuring claws on the main ruler and the sliding vernier named the inner measuring claws and outer measuring claws, that inner measuring claws are usually used to measure the inner diameter, and the outer measuring claws are usually used to measure the length and outer diameter.
