Brown & Sharpe 599-603-123-3 Vernier Depth Gauge, Micrometer Type, 0-3" Range, 0.0001" Graduation, +/-0.003mm Accuracy, 2.5" Base, 3 Rods

The Brown & Sharpe 599-603-123-3 Vernier Depth Gauge, Micrometer Type, Inch, has a measurement range of 0 to 3", and a resolution (or smallest graduation interval) of 0.0001", with + or - 0.003mm of accuracy. The vernier scale provides precise, fine measurements. This depth gauge has a hardened, precision base that is 2.5" long, and is used as a reference for measurements. It has a friction thimble for uniform measurements. The unit includes three 0.125" rods. The gauge conforms to the Deutsches Institut für Normung (DIN) 863 T2 (style T) and Norme Française (NF) E 11-097 standards. It has a satin-chrome finish for glare-free reading. The shipping weight for this gauge is 1.5 lb. and it comes with a fitted wooden 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.

Brown & Sharpe manufactures precision measuring equipment and metrology hand tools. The company, founded in 1833, is headquartered in North Kingstown, RI.
