Mitutoyo 323-350 Digimatic Disk Micrometer, Inch/Metric, 0.787" Dia. Disks, Ratchet Stop, Rotating Spindle, 0-1" (0-25.4mm) Range, 0.00005" (0.001mm) Resolution, +/-0.0002" Accuracy, Meets IP65 Specifications

The Mitutoyo 323-350 Digimatic digital disk micrometer is for measuring the root tangent length of spur gears and helical gears. The micrometer has a measurement range of 0 to 1.0" (0 to 25.4mm), resolution of 0.00005" (0.001mm), and an accuracy of + or - 0.0002". The LCD screen displays in inches and metric units. The measuring surfaces are disk-shaped, with a flat outer surface and a center recess, are 0.787" (20mm) in diameter, and have an edge thickness of 0.028" (0.7mm) for use in narrow spaces. This gauge has a ratchet stop to help provide uniform pressure for precise, repeatable measurements. It is Ingress Protection certified IP65 for protection against dust and water.

Additional functions offered by this micrometer include origin setting, zero setting, data hold, data output, and alarms for low voltage and counting value composition errors. This micrometer offers serial data output (using optional SPC cables, sold separately), which increases speed and reliability of digital measurement records. It has a battery life of approximately 1.2 years of normal use. This unit comes with a SR-44 battery and fitted, plastic case.

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.
