Dialindikaattoreita, known in English as dial indicators or dial gauges, are precision measuring instruments used to detect small variations in a surface. They are mechanical devices that amplify slight movements and display them on a graduated dial. A dial indicator typically consists of a plunger that moves in and out of a housing. As the plunger is pushed or pulled, it actuates a series of gears and levers, which in turn rotate a pointer on a circular dial face. The dial is usually marked with a scale, often in millimeters or thousandths of an inch, allowing for precise readings. Many dial indicators also feature a smaller sub-dial to indicate full revolutions of the main pointer.

These instruments are widely used in various fields, including manufacturing, machining, quality control, and engineering. They are essential for tasks such as checking for flatness, runout, parallelism, and concentricity of parts. Dial indicators are often mounted on magnetic bases or specialized stands to position them accurately against the workpiece being measured. Their simplicity, durability, and high precision make them a fundamental tool in many metrology applications. Different types of dial indicators exist, including those with a lug back for mounting, or those with a lever-actuated stylus for measuring in tight spaces.
