Spi MS170308011 Electronic Outside Micrometer 8 in IP54

Product Description

The SPI MS170308011 is an electronic outside micrometer designed for high-precision dimensional measurement in machining, manufacturing, and quality control environments. It measures up to 8 inches with a resolution of 0.000050 inches and an accuracy of 0.000200 inches, making it suitable for applications that demand tight tolerances. The carbide-tipped measuring face resists wear during repeated use on hardened workpieces. An IP54 rating provides protection against dust ingress and splash water, supporting reliable performance in shop-floor conditions. A friction thimble delivers consistent measuring pressure. The unit ships calibrated with NIST traceability certification included.

This micrometer is used in precision machining shops, tool rooms, metrology labs, and quality assurance departments for outside diameter and thickness measurements in the 0-to-8-inch range. It supports both absolute and incremental measuring modes, allowing technicians to zero at any point along the measuring range. The rotating spindle and friction thimble suit both bench-top and in-process inspection work. It is typically used by machinists, metrologists, and quality control inspectors working to tight engineering tolerances.

Compatibility

Designed as an OEM-style electronic outside micrometer for general outside diameter and thickness measurement applications requiring a 0-to-8-inch range with electronic readout.

Installation Notes

No permanent installation is required for this handheld measuring instrument. Before use, verify the micrometer is zeroed at the appropriate reference point per the manufacturer calibration procedure. Handle the measuring faces with care to avoid contact with abrasive surfaces that could affect accuracy. Battery replacement uses a standard LR44 cell; power down the unit before replacing the battery.
