Dial Indicator

Description

A dial indicator is a precision instrument used to measure small variations in a surface or object. It works by a spring-loaded plunger that moves in and out, translating these tiny movements into large, easy-to-read rotations of a needle on a circular dial face. This magnified reading allows you to see deviations as small as a thousandth of an inch or a hundredth of a millimeter. It is the essential tool for tasks like checking for runout on a rotating shaft, aligning machinery and parts with extreme accuracy, or comparing sizes to a known standard to ensure perfection in manufacturing and quality control.
