What is the main purpose of a dial caliper?

The primary function of a dial caliper is to measure distances with high precision. This instrument is designed to provide accurate measurements of various dimensions, such as the internal and external diameters, depth, and step measurements of objects. The dial on the caliper allows for easy reading of the measurements, often enabling precision down to fractions of a millimeter or thousandths of an inch.

Dial calipers are widely used in mechanical engineering, machining, and manufacturing settings, where precise measurements are essential for quality control and fitment of parts. Their ability to give quick and accurate readings makes them a valuable tool in any workshop or technical field that requires detailed dimensional analysis.
