The Mitutoyo 293-349-30 digital micrometer has a 0 to 1" (0 to 25.4mm) measuring range with 0.00005" (0.001mm) increments for precision and a friction thimble stop with carbide-tipped measuring faces for consistent measurement. Its digital readout LCD shows inch or metric units for versatility and a Hold button saves a measurement for reading later. The digital micrometer is Ingress Protection certified IP65 for protection from dirt and water and includes a protective case and SR44 silver oxide battery.

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.

Mitutoyo manufactures precision measuring tools, metrology equipment, and related systems. The company, founded in Tokyo in 1934, formed Mitutoyo America Corporation in 1963 with headquarters in Aurora, IL.
