Mitutoyo 293-335-30 Electronic Outside Micrometer 1 in

Product Description

The MITUTOYO 293-335-30 is a digital outside micrometer built for precision measurement in demanding shop and field environments. It measures external dimensions up to 1 inch with a resolution of 0.000050 inches and an accuracy of 0.000050 inches, making it suitable for tight-tolerance inspection work. The measuring faces are solid carbide, which resists wear during repeated use on hard materials. The satin chrome finish reduces glare under shop lighting. An IP65 rating protects the electronic components against dust ingress and low-pressure water jets. A licensed metrology technician, machinist, or quality control inspector is the typical end user for this instrument.

The 293-335-30 is used in precision machining, quality assurance, and dimensional inspection applications where digital readout and high accuracy are required. It fits standard outside micrometer workflows for measuring shafts, pins, stock thickness, and similar external features up to 1 inch. The friction thimble ensures consistent measuring force, which reduces operator-to-operator variation in readings. The rotating spindle allows fine adjustment during measurement. It ships with a certification of inspection and a plastic carrying case, supporting traceability requirements in documented inspection processes.

Compatibility

Designed as an OEM-specification electronic outside micrometer for standard 0- to 1-inch measurement applications in machining, inspection, and quality control environments.

Installation Notes

This instrument is calibrated before shipment and should be zeroed according to the included documentation before first use. Handle the carbide measuring faces with care to avoid contact with abrasive surfaces outside of intended measurement. Store in the included plastic case when not in use to protect the electronic components. Battery replacement uses a standard SR44 cell; power down the unit before replacing the battery.
