The Mitutoyo Series 184 feeler gauge is available in measurement ranges of 0.03 to 0.05mm, 0.05 to 0.08mm, or 0.05 to 1.0mm. The straight 13mm width leaf is available in 100mm or 150mm lengths. Thickness is marked on each leaf for convenient use. A knurled locking nut holds a leaf in place during use and an integrated steel case protects the leaves when not in use. This feeler gauge is suitable for precise measurement in a variety of mechanical applications.

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.
