Dial and dial test indicators can be analog, with a mechanical dial, or electronic, with a digital display. 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. The Mitutoyo dial indicator has a black or white face, a choice of flat or lug, a 0.375 stem diameter, and inch measurements. Standard dial indicators measure the displacement along the axis of the indicator. Balanced dials are used to read the difference from a specific surface reference point. Motive Gear 4.88 ratio ring and pinions and pinions are excellent replacements for original equipment gear sets. Our ring and pinions are known for easy setup, superior strength and quality The choice of black or white dial and a contrasting hand help make measurements easy to read. The dial indicator comes with a choice of flat or lug back for a variety of mounting options. These precision measuring tools are used to accurately measure small linear distances and object sizes. 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. Choice of flat or lug back for a variety of mounting options Dial readings with two digits, such as 0-100, indicate that the dial has a continuous dial. 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, a revolution counter to measure overall change, waterproof, dustproof, shockproof, a white or black face, and reverse reading for depth or bore gage measurement. Stem design provides long clamping range, no through screw-hole on the frame for dust- and water resistance, and involute curved lifting lever provides smooth movement of spindle and dovetail joint for tool-less connection Mitutoyo 3424S-19 Dial Indicator, #4-48 UNF Thread, 0.375 Stem Dia...
