Mitutoyo 547-217S ABSOLUTE Digimatic LCD Depth Gauge, Indicator Type, 0-8"/0-200mm Range, 0.0005"/0.01mm Graduation, +/-0.001" Accuracy, 2.5" x 0.63" Base

The Mitutoyo Series 547 ABSOLUTE Digimatic LCD Depth Gauges, Indicator Type, Inch/Metric, depending on the model, have a measurement range of 0 to 8" (0 to 200mm), a stroke (or travel distance of the indicator) of 0.5", and a resolution (or smallest graduation interval) of either 0.0005" (0.01mm) with + or - 0.001" of accuracy, or 0.00005" (0.001mm) with + or - 0.0003" of accuracy. The LCD screen displays in both inches and metric, and can keep track of the origin point for the life of the battery (about 3.5 years under normal use). The gauges come with four measuring extension rods for flexibility. The bases of the units (either 2.5" or 4"long) are hardened, ground, and lapped for durability and accuracy. The units support Mitutoyo's data output signal (SPC Output) for devices. Optional SPC cables for use with Mitutoyo devices and extension rods are sold separately. Depth gauges are typically used in manufacturing, machining, and mechanical engineering.

Depth gauges are precision measuring instruments used to determine the depth of any shape that has a step, groove, or slot. These gauges often take the form of sliders that travel on a measuring beam or rods, are moved to position by hand, and then adjusted with a calibrated screw. The base of the gauge rests at the top of the shape whose recession is to be measured, while the beam or rods extend to the bottom of the recession to determine the measurement. Gauge position is read from a graduated scale, dial, counters, or an electronic display.

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.
