A caliper used for measuring the diameter of a circle.

Caliper

A caliper used for measuring the diameter of a circle.

This caliper was commonly used in projects that required great precision. The object of interest is placed in the opening, measured and then removed.

These calipers are used to measure the external size of an object. The same observations and technique apply to this type of caliper, as for the above inside caliper. With some understanding of their limitation and usage these instruments can provide a high degree of accuracy and repeatability. They are especially useful when measuring over very large distances, consider if the calipers are used to measure a large diameter pipe.
