Mitutoyo 293-230-30 Electronic Outside Micrometer IP65

Product Description

The MITUTOYO 293-230-30 is an electronic outside micrometer designed for high-precision dimensional measurement in demanding shop and field environments. Built with a solid carbide measuring face and a satin chrome finish, this instrument delivers a resolution of 0.00005 inches and an accuracy of 0.0001 inches. The ratchet stop thimble provides consistent measuring force, reducing operator-to-operator variation. Rated IP65, the unit resists dust ingress and low-pressure water jets, making it suitable for use in coolant-present machining environments. It ships with a SR44 battery installed, a certification of inspection, and a plastic protective case.

This micrometer is used across precision machining, toolroom inspection, quality control, and maintenance applications where outside diameter or thickness measurements require tight tolerances. The IP65 rating extends its service life in wet or oily environments typical of CNC machine shops, grinding operations, and general metalworking. The 25.00 mm throat depth accommodates a range of workpiece geometries. Machinists, metrologists, and quality technicians are the primary users of this instrument.

Key Features

• Solid carbide measuring faces for extended wear resistance and measurement consistency
• IP65-rated protection against dust and water spray in shop environments
• Resolution of 0.00005 inches for fine measurement discrimination
• Accuracy of 0.0001 inches per proprietary inspection certificate standard
• Ratchet stop thimble ensures repeatable, consistent measuring force
• Includes certification of inspection and plastic carrying case

Compatibility

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

Installation Notes

Electronic outside micrometers require no installation but should be handled by qualified metrology or machining personnel familiar with proper gauge care. Before use, verify zero calibration against a known standard and allow the instrument to thermally stabilize to ambient shop temperature. Avoid dropping or storing near strong magnetic fields, as these conditions can affect electronic accuracy. Replace the SR44 battery when the low-battery indicator activates to maintain measurement integrity.
