The Mitutoyo 223-125 disk outside micrometer has a 0 to 1" measuring range with 0.001" graduations and accuracy to 0.0002" for measuring root tangent length of gear teeth. It has a mechanical digit counter for quick reading of inch measurements and a satin chrome finish for clear visibility of the graduations. Its ratcheting thimble stop provides a constant force for consistent measurements and the rotating spindle with carbide-tipped measuring faces is durable. The disk outside micrometer comes with a fitted plastic case and is suitable for applications such as quality control for machined parts.

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.
