What is a dial caliper?

A dial caliper is a precision measuring tool used to accurately measure outside dimensions, inside dimensions, and depth measurements. It consists of a stationary main scale with a sliding scale that can be moved along the main scale to take measurements.

The dial caliper provides measurements in both metric and imperial units, making it versatile for a wide range of applications. The sliding scale on a dial caliper is typically equipped with a dial gauge that displays measurements with high accuracy, usually to within 0.001 inches or 0.02 millimeters.

Dial calipers are commonly used in manufacturing, engineering, woodworking, metalworking, and other industries where precise measurements are required. They are convenient to use and provide accurate results, making them a popular choice for professionals and hobbyists alike.
