Mitutoyo 129-109 Vernier Depth Gauge, Interchangeable Rods, Micrometer Type, 0-50mm Range, 0.001mm Graduation, +/-0.0027mm Accuracy, 63.5mm x 16mm Base, 2 Rods

The Mitutoyo Series 129 Vernier Depth Gauge, Interchangeable Rods, Micrometer Type, Metric, depending on the model, have a measurement range of 0 to 50mm, 0 to 100mm, or 0 to 150mm, and a resolution (or smallest graduation interval) of 0.01mm. (See the product catalog for information on accuracy.) The vernier scale provides precise measurements. These gauges include interchangeable 4mm diameter measuring rods (2, 4, or 6 rods included, depending on the measurement range) 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 body for readability and the bases are made of hardened steel for durability and accuracy. They come in a fitted plastic case. 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.
