Mitutoyo 293-180-40 Electronic Outside Micrometer 1 in

Product Description

The MITUTOYO 293-180-40 is a digital outside micrometer designed for high-precision dimensional measurement in machining, toolmaking, and quality-control environments. Rated IP65 for protection against dust and coolant splash, this instrument handles the conditions of an active shop floor without compromising accuracy. It measures from 0 to 1 inch with a resolution of 0.000050 inches and a stated accuracy of 0.000050 inches, making it well suited for applications where tight tolerances are non-negotiable. The measuring faces are solid carbide, providing wear resistance over extended service life. A ratchet stop thimble delivers consistent measuring force with each reading.

The 293-180-40 fits production machining, tool and die work, and inspection stations where outside diameter, thickness, and step measurements must meet close tolerances. Its rotating spindle and satin chrome finish make it practical for both bench use and in-process checking. It ships complete with a fitted plastic case, inspection certificate, key wrench, and a CR2032 battery, so it is ready to calibrate and put into service immediately. This instrument is appropriate for machinists, metrologists, and quality technicians working to inch-based dimensional standards.

Compatibility

Designed as an OEM-style electronic outside micrometer for 0 to 1 inch measurement applications in machining and quality inspection settings.

Installation Notes

Electronic micrometers require no installation but should be zeroed and verified against a known standard before use. Store in the supplied fitted case when not in service to protect the measuring faces and electronics. Do not submerge the instrument; IP65 rating covers dust and directed water spray, not immersion. Battery replacement uses a standard CR2032 cell accessible via the battery compartment.
