Mitutoyo 543-558A Absolute LCD Digimatic Indicator ID-F, with Back-Lit LCD, #4-48 UNF Thread, 0.375" Stem Dia., 0-2"/0-50.8mm Range, +/-0.00012" Accuracy

Mitutoyo 543-558A IDF Digimatic Indicator with six user-selectable resolutions of 0.00005, 0.0001, 0.0005, or 0.001”, and 0.001 or 0.01 mm, an accuracy of + or - 0.00012” (0.003 mm), a total measurement range of 0-2” (0-50.8 mm), and can be set to zero at any spindle position for measuring in either or both directions (plus or minus). The LCD display has a sealed housing that meets Ingress Protection Rating 30 (IP30) standards for dust and water protection, a 3/8” diameter stem, a steel ball contact point, and a flat back. The indicator displays maximum and minimum read hold, changes color from green to red when user-defined tolerances are exceeded, and has total indicator reading (TIR) capability that displays the absolute difference between the highest and lowest readings. A backup memory function retains user-defined setup conditions when power is interrupted, and an alarm indicates overflow errors, tolerance limit setting errors, and scale contamination. The indicator has SPC data output features that allow for data analysis, and choice of two power sources (AC or 9V battery).

Dial indicators may also be 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. 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.

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.
