Mitutoyo 293-676-20 Electronic Outside Micrometer IP65

Product Description

The MITUTOYO 293-676-20 is a digital electronic outside micrometer designed for high-precision linear measurement in industrial and trade environments. It measures up to 1.2 inches with a resolution of 0.000050 inches and an accuracy of 0.000100 inches, making it suitable for applications where tight tolerances are critical. The measuring faces are solid carbide, providing wear resistance for repeated use. A ratchet friction thimble delivers consistent measuring force to ensure repeatable readings. The unit carries an IP65 rating, meaning it is protected against dust ingress and low-pressure water jets — a practical feature in shop or field environments where coolant, chips, or moisture are present. Licensed machinists, toolroom technicians, and precision measurement professionals are the primary users.

This micrometer is used in manufacturing, machining, toolroom, and quality control applications that require outside diameter or thickness measurements at fine resolution. It is appropriate for both production floor and inspection room use. The 25.00 mm throat depth accommodates a range of workpiece geometries. The instrument includes one SR44 battery and ships with a plastic protective case, making it ready for immediate deployment. It suits any setting where digital readout and IP-rated protection are preferred over conventional analog instruments.

Compatibility

Designed as an OEM-specification electronic outside micrometer suitable for standard outside diameter and thickness measurement applications in machining, manufacturing, and inspection environments.

Installation Notes

This instrument requires no installation in the traditional trade sense, but calibration verification against a known standard is recommended before first use and at regular service intervals. Store the micrometer in the included plastic case when not in use to protect the measuring faces and electronics. Avoid exposing the unit to impact or dropping, as this can affect calibration. Battery replacement uses a standard SR44 cell and should be performed with clean, dry hands to avoid contamination of the contact surfaces.
