what are Calipers


Calipers are generally of two types inside and outside to make internal or external measurements. They do not have direct scale reading. They transfer the measurement from jobs to scale or vice versa. Fig.1 shows a simple outside caliper. The caliper is held in a rule as shown in Fig.2 to read the size. It is used to make external measurement such as thickness of plates, diameter of sphere and cylinders. Fig.3 shows the standard spring joint outside caliper.
