Spi CMS220519057 Electronic Inside Micrometer 62-75mm

Product Description

The SPI CMS220519057 is an electronic inside micrometer designed for precision internal bore measurement in professional metrology, machine shop, and quality control environments. The instrument covers a measurement range of 62.00 to 75.00 mm and delivers an accuracy of +/-0.00010 inches, making it suitable for tight-tolerance inspection work. It features a ratchet stop thimble for consistent, repeatable measuring force and solid carbide measuring faces that resist wear during high-cycle use. A data output port allows integration with SPC data collection systems. The unit ships calibrated and battery-ready with a 3V CR2032 lithium cell included.

This inside micrometer is used in precision manufacturing, toolroom inspection, and quality assurance settings where internal diameter measurement in the 62.00 to 75.00 mm range is required. The extension rod design supports a maximum extension rod length of 6 inches and a gage depth of 114.00 mm, enabling reach into deeper bores. It is installed and operated by machinists, metrologists, quality technicians, and precision measurement professionals working to dimensional tolerances in industrial or production environments.

Installation Notes

This instrument is operated by trained metrology or machine shop personnel and does not require permanent installation. Prior to use, verify calibration status and zero the instrument against the included or appropriate setting ring. Keep measuring faces clean and free of chips, coolant, and debris to maintain accuracy. Store in the provided case when not in use to protect the carbide faces and electronic components.
