The Brown & Sharpe Digital Micromaster micrometer has a digital single-value LCD readout that displays in inch and metric units with resolution to 0.00005" (0.001 mm) for outside diameter (OD) measurement.

The micrometer's electronic microprocessor can hold measurements at any position, convert to absolute value, set a temporary zero position, and return to a true zero reading. An automatic off function helps preserve battery life when the unit is not in use. The spindle and anvil have flat measuring faces and are tungsten carbide-tipped for wear resistance. The micrometer's knurled friction drive thimble mechanism helps provide uniform pressure during adjustment for precise, repeatable measurement. A spindle lock helps provide secure locking of the measurement position. The micrometer includes, and is powered by, a single CR2032 lithium cell battery, and comes with a plastic case for storage.

Micrometers are precision measuring instruments that use a calibrated screw to measure distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot.

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