Spi CMS220519047 Electronic Inside Micrometer 6-8mm

Product Description

The SPI CMS220519047 is an electronic inside micrometer designed for precision internal bore and hole measurements in the 6.00 to 8.00 mm range. Built with an alloy steel measuring face and a ratchet stop thimble, it delivers consistent, repeatable readings with an accuracy of plus or minus 0.00010 inches. The instrument includes data output capability, allowing technicians to connect readings directly to statistical process control or data-logging systems. It ships calibrated and battery-ready with a 3V CR2032 lithium cell included. Machinists, tool-and-die makers, and quality control technicians use this instrument in precision manufacturing and inspection environments.

This inside micrometer is suited for measuring small internal diameters in machined bores, bushings, and precision housings where tight tolerances must be verified. The extension rod type design allows the gauge depth to reach 53.50 mm, making it practical for recessed or deep-bore inspection. It is appropriate for both production floor and metrology lab use where electronic data capture is required alongside manual measurement verification.

Key Features

• Measurement range of 6.00 to 8.00 mm for small internal bore inspection
• Accuracy of plus or minus 0.00010 inches for high-precision tolerance verification
• Alloy steel measuring face for durability and wear resistance
• Ratchet stop thimble provides consistent measuring pressure across readings
• Data output port supports direct connection to SPC or data-logging systems
• Ships factory calibrated with a 3V CR2032 lithium battery included

Compatibility

Designed as an OEM-style precision instrument for use in standard inside micrometer applications requiring small-bore measurement in the 6.00 to 8.00 mm range with electronic data output.

Installation Notes

This instrument is handled and operated by machinists, metrologists, or quality inspection personnel — not a field-installed component. Before use, verify calibration status and ensure the measuring faces are clean and free of debris. Handle the measuring faces with care to avoid damage to the alloy steel contact surfaces. Store in the provided case when not in use to protect calibration and surface integrity.
