Mitutoyo 543-562A, IDH Digimatic Indicator has five user-selectable resolutions of 0.00002”, 0.00005”, or 0.0001”, and 0.0005 or 0.001 mm, an accuracy of + or - 0.00005”/0.0015 mm, and a total measurement range of 0 - 1.2 inches/0 - 30.4 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, an 8-mm 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 low voltage and overflow, tolerance limit setting, and counting value composition errors. The indicator has remote control functionality, RS-232C data input and output, and SPC data output features that allow for data analysis, and a choice of two power sources (AC or 9V battery).

Dial indicators, also called dial gauges, dial calipers, and probe indicators, are precision measuring tools used to measure small linear distances and object sizes. The dial magnifies the measurement for readability by the human eye. They are frequently used in manufacturing, laboratories, and other industrial or mechanical fields, and are suitable anywhere a small measurement must be taken 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.

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.
