Product Description

The Mitutoyo Series 128 Vernier Depth Gauge, Micrometer Type, Inch, have a measurement range 0 to 1", a resolution (or smallest graduation interval) of 0.001", with + or 0.0001" of accuracy. The vernier scale provides precise measurements. These gauges include a 4mm diameter measuring rod for flexibility in measuring range. The units have a ratchet stop for uniform pressure and a measuring rod clamp for stability. They have a satin chrome finish on the thimble for readability. They are available in with a base either 2.5" or 4" long. 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 therecessionto 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.
