Mitutoyo 293-181-40 Electronic Outside Micrometer 1-2 in

Product Description

The MITUTOYO 293-181-40 is an electronic outside micrometer with a measurement range of 1 to 2 inches, designed for high-precision dimensional inspection in machining, manufacturing, and metrology environments. The Quantumike series instrument delivers a resolution of 0.000050 inches (0.001 mm) and an accuracy of 0.000050 inches, making it suitable for applications where tight tolerances are critical. The measuring faces are solid carbide for long service life under repeated contact with hardened workpieces. A ratchet stop thimble ensures consistent measuring force, and the IP65 rating protects the electronics against dust ingress and low-pressure water jets. Machinists, quality control technicians, and toolroom professionals are the primary users of this instrument.

The 293-181-40 is suited for precision measurement tasks in both job shop and production environments. The 1-to-2-inch range covers a common class of turned, ground, and milled components. The satin chrome finish reduces glare under shop lighting. A rotating spindle is included. The unit ships with a fitted plastic case, an inspection certificate, a key wrench, and a CR2032 battery installed, so it is ready for immediate use out of the box. It is appropriate for incoming inspection, in-process gauging, and final part verification where documentation of accuracy traceability is required.

Compatibility

Designed as an OEM-specification electronic outside micrometer for dimensional inspection of workpieces in the 1-to-2-inch range; compatible with standard micrometer stands and fixtures that accept conventional outside micrometer frames.

Installation Notes

This instrument requires no installation in a fixed system but should be handled and stored by qualified metrology or machining personnel following calibration and care procedures. Before use, verify the zero setting and clean the measuring faces with a lint-free cloth. Do not apply excessive clamping force or drop the instrument, as this can affect calibration. The CR2032 battery can be replaced using the included key wrench without exposing internal electronics, provided the IP seal area is kept clean and undamaged.
