Starrett 655-3041J Dial Indicator, 0 to 3" Range, 0.001" Graduations, Lug-Type Back, Jewelled Bearings

The Starrett 655-3041J dial indicator has a 0 to 3" measuring range with 0.001" graduations for precise measurements. It has a 0 to 100 counter with one revolution equivalent to 0.1", and jewelled bearings for smooth operation. The white-face dial with scratch-resistant crystal face is easy to read. It has a lug-type dial back for mounting. The dial indicator has a stainless-steel stem with a hardened steel spindle for durability, and 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 work piece. 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 analogue, 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. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.
