Starrett 1017-4 Caliper Gauge, Pointed Jaw, White Face, 0-2" Range, 0.001" Resolution

The Starrett outside dial caliper gauge opens to 2" with 0.001" dial graduations, one full rotation equaling 0.1". The gauge has carbide ball contacts for longer life and wear resistance. The deep opening reaches over the workpiece, such as in castings and sheet metal, to measure small sections of that workpiece. The retraction lever allows for one-handed use and gauge control, while a direct reading dial hand for accuracy.

Dial indicators, also called dial gauges or probe indicators, are precision measuring tools used to accurately measure small linear distances and object sizes. The dial magnifies the measurement so that it can more easily be 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. Dial test indicators are very similar to dial indicators, except that the axis of measurement is perpendicular to the axis of the indicator. Standard dial indicators measure the displacement along the axis of the indicator. Dial 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.

The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
