These micrometers have a round anvil for measuring the wall thickness of pipe, tubing, and other curved surfaces. All have a ratchet-stop thimble with a speeder knob to reduce the time it takes to open and close the micrometer. A constant-force mechanism stops the micrometer’s spindle from tightening once it contacts the surface of the measured object. This ensures repeatable measurements and prevents over-tightening. When the spindle stops tightening, the thimble stops turning, but the speeder knob will continue turning with a clicking sound.

395 models display measurements on an easy-to-read LCD. They have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the micrometer is turned off. A zero-set button allows you to start measuring at any point.

USB data cables (sold separately) connect 395 model micrometers directly to your PC.

10-pin data cables (sold separately) connect 395 model micrometers to a Mitutoyo miniprocessor or multiplexer.

Wireless data transmitters and receivers (sold separately) let you send data from 395 model micrometers to your PC without a cable.
