Spi CMS220519056 Electronic Inside Micrometer 50-63mm

Product Description

The SPI CMS220519056 is an electronic inside micrometer designed for precision internal bore and hole measurement. It covers a measurement range of 50.00 to 63.00 mm and delivers an accuracy of plus or minus 0.00010 inches, making it suitable for tight-tolerance inspection work in machine shops, manufacturing facilities, and metrology labs. The ratchet stop thimble provides consistent measuring pressure, and the solid carbide measuring faces resist wear during repeated use. A data output port allows integration with SPC software or digital recording systems. The unit ships calibrated and battery-ready.

This inside micrometer is intended for professional metrology applications where internal diameter verification is required on bores, cylinders, and machined features falling within the 50.00 to 63.00 mm range. The extension rod design accommodates varying gage depths up to 90.00 mm. It is used by machinists, quality control technicians, toolroom professionals, and precision measurement specialists working to tight drawing callouts in industrial and manufacturing environments.

Key Features

Compatibility

Designed as an OEM-style precision inside micrometer for professional metrology and quality control applications requiring internal measurement in the 50.00 to 63.00 mm range.

Installation Notes

This instrument is installed and operated by qualified metrology technicians or machinists familiar with inside micrometer technique. Before use, verify calibration against the included setting ring. Store the micrometer in its case away from temperature extremes and contaminants that can affect measurement accuracy. Do not over-tighten the thimble beyond the ratchet stop, as excess force will compromise reading accuracy and may damage the measuring faces.
