The Starrett 3753 Electronic Depth Gauge without Output, has a measurement range of 0 to 8" (0 to 200mm), and a resolution (or smallest graduation interval) of 0.0005" (0.01mm) with + or – 0.001" (0.03mm) of accuracy. The LCD screen displays in both inches and metric. The base is 2.75"(70mm) long, and the body and the slide are made of hardened stainless steel for durability. Control buttons offer Zero at any position, Hold at any position, and Limits functions. These gauges include one CR2032 lithium battery. Larger bases and additional batteries are sold separately. 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 L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.
