Key Features

  • Spherical anvil and spindle faces for measuring tubing wall thickness
  • Digital, single-value readout LCD displays in inches and metric units for readability
  • Statistical Process Control (SPC) output transmits results to a computer or external device through an interface cable (sold separately)
  • Ratchet-stop mechanism helps provide uniform pressure for precise, repeatable measurements
  • Rated IP65 for resistance to penetration by dust and liquid up to the force of a low-pressure water jet

Product Description

The Mitutoyo 395 series outside micrometer has spherical anvil and spindle faces appropriate for measuring the wall thickness of tubing. It also has a ratchet-stop mechanism, an LCD digital readout that converts between inches and metric with resolution to 0.00005” (0.001mm) for outside diameter (OD) measurement, and Statistical Process Control (SPC) data output to transmit results to a computer or external device. The output jack transmits SPC results to a computer through an interface cable (sold separately). 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. The electronics housing has an Ingress Protection 65 (IP65) rating, for protection against penetration by dust, liquids, and coolant up to the force of a low-pressure (to 30 kilonewtons/meter-squared) water jet. The steel frame has a black, heat-insulated finish, and the thimble and sleeve have a glare-free, satin chrome rust- and glare-resistant finish. The micrometer’s knurled friction thimble and ratchet-stop mechanism to help provide uniform pressure for precise, repeatable measurement during adjustment. A lock nut helps ensure quick spindle locking. The unit comes with an SR44 battery and a fitted plastic case.

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.

Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
