Fowler 54-225-555 Xtra-Value Depth Gage

The Fowler 54-225-555 Xtra-Value Depth Gauge has a measurement range of 0 to 16" (0 to 405mm), and a resolution (or smallest graduation interval) of 0.0005" (0.01mm), with + or 0.001" (0.02mm) of accuracy. The gauge includes five measuring rods and has a spring-loaded measurement button with a hold function for ease of use and accurate measurements. Depth gauges are typically used in manufacturing, machining, and mechanical engineering. Depth gauges are precision measuring instruments used to determine the depth of a 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. Fowler, an American company, manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA. What's in the Box?
