Dial indicators, or dial gauges, are mechanical display instruments used to provide a readout of some small measurement not immediately discernable to the naked eye. Common dial indicators incorporate a dial display with arms and graduations on a circular scale, similar to a clock face. Internally, dial indicators incorporate a rack and pinion gear to read its probe position. In machining, dial indicators can be used to inspect variations in tolerance of machined parts, beam, ring, or rod deflection from its axis, calibrate a machine, manufacture precision tools, centering a workpiece in a lathe, inspecting for lateral run-out of a rotor, and other small measurements.
