Fowler 54-004-255 Xtra-Value Depth Gauge & Poly-Cal Measuring Set, 1-6" Depth Gauge and 6" Poly-Cal

The Fowler 54-004-255 Xtra-Value Depth Gauge & Poly-Cal Measuring Set includes two depth gauges: the Poly-Cal Electronic Caliper (54-101-175) and the Xtra-Value Depth Gauge (54-225-555). The Poly-Cal Electronic Caliper is made of polycarbonate and has a measurement range of 0 to 6" (0 to 150mm), and a resolution (or smallest graduation interval) of 0.0005" (0.01mm), with + or – 0.008" (0.2mm) of accuracy. The Xtra-Value Depth Gauge has a measurement range of 0 to 6" (0 to 150mm), and a resolution of 0.0005" (0.01mm), with + or – 0.001" (0.025mm) of accuracy. The LCD screen for both gauges display in U.S./metric, and fractions (in 1/64" increments). The Xtra-Value gauge includes six measuring rods and has a spring-loaded measurement button with a hold function for ease of use and accurate measurements. The gauges conform to Federal Accuracy specifications. The shipping weight of the set is 1.2 lb. and it comes with a hardened 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.

The Fred V. Fowler 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.
