These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Change out the steel extension rods supplied in 1" incremental lengths to measure the depth of holes, slots, shoulders, and projections. The thimble has a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening.

Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position when the micrometer is turned off. A zero-set button lets you start measuring at any point. SPC data output allows for connection to a computer or data processor.

USB data cable (sold separately) connects the micrometer directly to your PC.

10-pin data cables (sold separately) connect the micrometer to a Mitutoyo miniprocessor or multiplexer.

Wireless data transmitter and receiver (sold separately) allow you to transmit measurement data from the micrometer to your PC without being tethered by a cable.
