Mitutoyo 293-832-30 Electronic Outside Micrometer 1 in

Product Description

The MITUTOYO 293-832-30 is a digital electronic outside micrometer designed for high-precision linear measurement in machining, metrology, and quality-control environments. It measures up to 1 inch with a resolution of 0.000050 inches and an accuracy of 0.000100 inches, making it suitable for close-tolerance inspection work. The measuring faces are solid carbide for wear resistance and long-term dimensional stability. A friction thimble delivers consistent measuring force across repeated measurements, reducing operator-induced error. This instrument is used by machinists, tool-and-die makers, QC inspectors, and precision fabricators who require reliable, repeatable outside-diameter and thickness readings.

The 293-832-30 suits residential shop, industrial production floor, and laboratory inspection applications where outside dimensions must be verified to sub-thousandth accuracy. It is appropriate for measuring shafts, pins, stock thickness, and machined components. The satin chrome finish reduces glare under shop lighting. The unit ships with a certification of inspection and a plastic carrying case, making it field-ready for both bench and on-machine use.

Key Features

• 0.000050-inch resolution for sub-thousandth measurement precision
• 0.000100-inch accuracy across the full 1-inch measuring range
• Solid carbide measuring faces resist wear and maintain calibration longer than standard steel faces
• Friction thimble provides constant measuring force for repeatable readings
• Satin chrome finish minimizes glare and corrosion in shop environments
• Includes SR44 battery, certification of inspection, and plastic case

Compatibility

Designed as a direct-use electronic outside micrometer for any application requiring outside measurement up to 1 inch. No specific system integration is required; it operates as a standalone handheld precision instrument.

Installation Notes

No installation is required. Insert the included SR44 battery before first use. Prior to measuring, clean the anvil and spindle faces and verify zero calibration using the supplied standard or a verified gauge block. Do not overtighten the thimble or apply force beyond what the friction clutch allows, as this can affect accuracy and damage the spindle.
