Mitutoyo Electronic Calipers

All calipers have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the caliper is turned off. A zero-set button allows you to start measuring at any point.

USB data cable (sold separately) connects calipers with SPC data output directly to your PC.

10-pin data cables (sold separately) connect calipers with SPC data output to a Mitutoyo miniprocessor or multiplexer.

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

Display freeze adapter (sold separately) keeps a measurement displayed on calipers with SPC data output even if the jaw is repositioned.

Depth base attachments (sold separately) stabilize the caliper when taking depth measurements.
