The Mitutoyo 2776S dial indicator is used to measure surface variations. It has a measurement range of 0 to 1.0", graduations of 0.0005", an accuracy of + or – 0.002", and a range per revolution of 0.05". The dial is white with a contrasting hand for readability. The stem design provides a long clamping range, there are no through screw-holes on the frame for dust- and water resistance, and it has a lug back for mounting from the rear of the indicator. This unit has a 3/8" diameter stem and a #4-48 UNF contact point thread mount. The dial is continuous with a reading of 0-50, for direct readings. It has a force of 2.5 Newtons (N) or less.

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.
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.
Mitutoyo manufactures precision measuring tools, metrology equipment, and related systems. The company, founded in Tokyo in 1934, formed Mitutoyo America Corporation in 1963 with headquarters in Aurora, IL.
