The Mitutoyo 389-351 digital outside micrometer has a 0 to 1"/0 to 25.4mm measuring range with 0.00005"/0.001mm resolution and accuracy to 0.0002" for measuring thickness of material such as sheet metal, paper, and plastic. It has a 6" throat depth, LCD screen, and SPC data output. The 6" throat depth provides extended range for measuring the thickness of material such as sheet metal, paper, and plastic. The LCD and function buttons allow origin-set, zero-set, data hold, and inch/mm conversion, and the Statistical Process Control (SPC) data output allows connection to a computer with an optional SPC cable (sold separately). An alarm indicates low battery. Its ratcheting thimble stop provides a constant force for consistent measurements. The carbide-tipped measuring faces are flat to 0.000024"/0.6μm. It is supplied in a fitted plastic case. The digital outside micrometer has an Ingress Protection 65 (IP 65) rating level for protection against dust and liquids such as coolant, 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.
