Spi CMS220519058 Electronic Inside Micrometer 75-88mm

Product Description

The SPI CMS220519058 is an electronic inside micrometer designed for precise internal bore and hole measurement within a range of 75.00 to 88.00 millimeters. It delivers an accuracy of plus or minus 0.00020 inches, making it a reliable tool for machinists, quality control technicians, and metrology professionals who require tight-tolerance verification. The micrometer features a ratchet stop thimble for consistent measuring force and an extension rod design that allows reach into deeper bores. Solid carbide measuring faces resist wear during repeated use. The unit includes data output capability for integration with SPC or quality documentation systems.

This inside micrometer is suited for production floor and inspection room environments in manufacturing, tooling, and precision machining operations. The extension rod configuration supports measurement at a gage depth of 114.00 millimeters, reaching deeper workpiece features that standard non-extendable micrometers cannot access. A maximum extension rod length of 6 inches expands versatility across a range of bore depths. The instrument ships calibrated and battery-ready with a 3V CR2032 lithium battery included, allowing immediate use upon receipt.

Installation Notes

This instrument is handled and calibrated by quality technicians or metrology staff — not a field-installed component. Store in the provided case to protect the measuring faces and spindle. Zero and verify calibration against a certified setting ring (3.5000 inches diameter) before use. Avoid exposing the unit to cutting fluids, extreme temperatures, or impacts that could affect calibration integrity.
