Starrett Universal Dial Test Indicator Set with Back Plunger - White Face, 0-100 Reading, 200" Range, .001" Graduation, 1/4" Shank Diameter for Mounting - 196B1

The Starrett 196 series universal dial indicator has a 0 to 0.2" measuring range with 0.001" graduations for precise measurement of the rise or drop in a work piece. It has a 0 to 100 counter with one revolution equivalent to 0.1", and the white-face dial has a scratch-resistant crystal face for ease of reading. The plunger on the back of the dial comes with 1/2", 5/16", and 1/8" diameter contact points. The dial indicator has a 1/4" diameter stainless-steel shank for mounting. Some dial indicator sets include an adapter, a standard letter of certification, and clamp, tool post holder, snug, and hole attachments. The dial indicator is suitable for applications such as quality control for machined parts.

Dial indicators are also called dial gauges, probe, and electronic indicators. These precision instruments measure small linear distances and object sizes. The dial magnifies the measurement so that it can be easily read by the human eye. Frequently used in manufacturing, laboratories, and other industrial or mechanical fields, dial indicators are used anywhere a small measurement must be found and recorded or transferred, such as checking the variation in tolerance of a workpiece. Standard dial indicators measure the displacement along the axis of the indicator. Dial test indicators are very similar to dial indicators, except that the axis of measurement is perpendicular to the axis of the indicator. Dial and dial test indicators can be analog, with a mechanical dial, or electronic, with a digital display. Some electronic models transfer the data electronically to a computer for recording and potential manipulation.
