The Mitutoyo 513 series pocket type dial test indicator has a white face, a 0.375" stem diameter, and inch measurements. The indicator has a reversible measuring direction and an adjustable contact point, and is used to measure surface variations in narrow or recessed areas. The pocket-type dial test indicator has a horizontal face and three dovetail mounts, and can be mounted either horizontally or vertically from either the front, top, or back of the indicator. It has jeweled bearings that provide high sensitivity and accuracy, a reversible measuring direction, and a contact point that can be adjusted within 220 degrees of the axis. This dial indicator meets Japanese Industrial Standard (JIS) B7533-1990. The basic set includes a dial indicator, a 0.079" carbide contact point, a 3/8" diameter stem, a knurled clamp ring, and a plastic storage box.

Dial readings with three digits, such as 0-10-0, signify that the indicator has a balanced dial. Dial readings with two digits, such as 0-100, indicate that the dial has a continuous dial. Balanced dials are used to read the difference from a specific surface reference point. Continuous dials are used for direct readings and usually have a larger measurement range than balanced dials. Optional features include jeweled bearings for high sensitivity and accuracy, and a white face.

Dial indicators are also called dial gauges, dial calipers, and probe indicators. These precision measuring tools are 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. 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 systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
