What is measured by a digital caliper?

A digital caliper is a versatile tool designed to measure both internal and external distances accurately. It consists of two sets of jaws, one for measuring the external dimensions of an object and another set for measuring internal dimensions. This dual functionality makes it an essential tool for machinists and technicians alike.

In detail, the external jaws of a digital caliper can measure the width, height, or diameter of an object, while the internal jaws are used to measure the internal dimensions, such as the diameter of a hole or the width of a groove. Additionally, many digital calipers come with a depth rod that allows the user to measure the depth of recesses or holes. This multifaceted approach to measurement is what makes digital calipers an invaluable instrument in various settings, including workshops and laboratories, ensuring precise measurements for a range of applications.
