About Starrett 749BZ-6RL Micrometer LCD Depth
The Starrett 749 Micrometer LCD Depth Gauges, Inch, depending on the model, have a measurement range of 0 to 6" (0 to 150mm) or 0 to 12" (0 to 300mm), a resolution (or smallest graduation interval) of 0.0001" (0.001mm), with + or – 0.0001" (0.001mm) of accuracy. The LCD screen displays in both inches and metric, with inch graduations on the shell and thimble. These units include 5/32" diameter measuring rods to cover the intended range. The bases of these gauges are 4" long, and all measuring surfaces are hardened, ground, and lapped for accuracy. These gauges have a ring-type knurled lock nut and a combination ratchet and speeder to stabilize the gauge for precise measurements. These gauges have an RS232 data transmission port for data transport and accuracy. The metal surfaces of these gauges have a satin chrome finish that resists rust and improves readability, and a glare-free black finish on the frame. Control buttons offer Zero at any position, Hold at any position, Preset, and Limits functions. These units include one 3V battery, two wrenches, and a protective 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 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.
