The Mitutoyo 293 series QuantuMike Coolant Proof LCD micrometer has a digital single-value LCD readout that displays in metric units with resolution to 0.001mm. A ratchet thimble mechanism helps provide uniform pressure for precise, repeatable measurement. It also has a non-rotating spindle that helps provide steady positioning during measurement, and a QuantuMike spindle that feeds at a rate of 2mm per revolution for a higher rate of productivity than a conventional mechanism. It uses the Mitutoyo ABSOLUTE electrostatic capacitance linear encoder to help prevent overspeed errors and help ensure repeatable, precise 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. Depending on the model, an output jack transmits Statistical Process Control (SPC) data results to a computer or external device through an interface cable (sold separately). The micrometer has an Ingress Protection 65 (IP65) rating, which means that components are resistant to penetration by dust and debris, and resistant to penetration by liquids and coolant up to the force of a low-pressure (to 30 kilonewtons/meter-squared) water jet. The spindle and anvil have flat measuring faces and are carbide-tipped for wear resistance. The micrometer includes, and is powered by, a single SR44 silver oxide battery, and comes with a plastic case for storage.

Micrometers are precision measuring instruments that use a calibrated screw to measure small 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.
