The Mitutoyo Series 571 ABSOLUTE Digimatic LCD Depth Gauge, Hook End Type, Inch/Metric have a measurement range for this series of 0 up to 8" (0 up to 200mm), and a resolution (or smallest graduation interval) of 0.0005" (0.01mm), with up to + or - 0.0015" 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 years under normal use). The bases are 100mm (3.94") long, and the measuring faces of the units are hardened, ground, and lapped for durability and accuracy. The gauges in this series conform to European Conformity (CE) marking and the Ingress Protection 67 (IP67) standard. The display has origin-set, zero, and data output functions for convenience. The units support SPC output. The gauges in this series include an SR44 battery. Optional SPC cables and a wider extension base 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.
