Spi CMS220519062 Electronic Inside Micrometer Set

Product Description

The SPI CMS220519062 is an electronic inside micrometer set designed for precise internal measurements in machining, metrology, and quality control applications. The set covers a range of 1 to 2 inches with a resolution of 0.0001 inches and an accuracy of 0.0002 inches. Carbide-tipped measuring contact points extend service life and maintain calibration under repeated use. A ratchet stop thimble ensures consistent measuring pressure across readings. The unit outputs data digitally and features a rotating spindle for ease of positioning. This tool is calibrated to ASME 89.1.13 standards and is suited for use by machinists, tool and die makers, and metrology technicians.

This inside micrometer set is used for measuring the internal diameter of bores, holes, and other internal features in precision manufacturing and inspection environments. The extension rod system allows reach into deeper bores, with a maximum extension rod length of 6 inches. The measuring contact points are specifically engineered to allow measurements near the bottom of blind holes, making the set practical for close-tolerance bore inspection work in both production and toolroom settings.

Compatibility

Designed as an OEM-style precision measurement instrument for use in standard internal micrometer applications conforming to ASME 89.1.13 specifications.

Installation Notes

This instrument is used by machinists and metrology technicians and requires no installation in the traditional sense. Before use, verify calibration against a known standard and ensure measuring faces are clean and free of debris. Handle carbide contact points carefully to avoid chipping. Store the set in its case when not in use to protect the measuring surfaces and electronic components.
