Mitutoyo 2803S-10CAL Dial Indicator with Calibration, #4-48 UNF Thread, 0.375" Stem Dia., Lug Back, White Dial, 0-5-0 Reading, 2.244" Dial Dia., 0-0.025" Range, 0.0001" Graduation, +/-0.0001" Accuracy

The calibrated Mitutoyo 2803-10CAL dial indicator is used to measure surface variations in fractional inches. It has a 0.375" diameter stem, a #4-48 UNF contact point thread mount, a measurement range of 0 to 0.025", graduations of 0.0001", and an accuracy of + or - 0.0001". The white dial and a contrasting hand help make measurements easy to read. This dial indicator meets ANSI standards, Japanese Industrial Standard (JIS) B7503-1997, and American Gage Design (AGD) standards for face and thread size, and bezel and stem diameter. Mitutoyo calibrated tools include a Certificate of Calibration that provides evidence that the tool has been calibrated and is within allowable error specifications. Mitutoyo calibrated tools are certified by Mitutoyo's American Association for Laboratory Accreditation-accredited calibration laboratory (A2LA Certificate #750-01) to the International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) 17025 International Standard for testing and calibration laboratories.

The dial indicator has a stem design that provides a long clamping range, no through screw-holes on the frame for dust- and water resistance, a lug back for mounting, and an involute curved lifting lever that provides smooth movement of spindle and dovetail joint for a tool-less connection. This dial indicator is shock proof and has a jeweled bearing type. This model has a balanced dial, with a reading of 0-5-0, to read the difference from a specific surface reference point. It has a force of 2.5 Newtons (N) or less.

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.
