Spi CMS220519055 Electronic Inside Micrometer 40-50mm

Product Description

The SPI CMS220519055 is an electronic inside micrometer designed for precision bore and internal diameter measurement. It covers a range of 40.00 to 50.00 mm and delivers an accuracy of plus or minus 0.00020 inches, making it a reliable tool for tight-tolerance inspection work. The measuring faces are solid carbide for long-term wear resistance. A ratchet stop thimble provides consistent, repeatable measuring pressure. This instrument is factory calibrated and includes data output capability, allowing readings to be sent directly to a data collection system or SPC software. It is intended for use by machinists, quality control technicians, and metrology professionals.

This inside micrometer is suited for precision measurement applications in manufacturing, machine shops, and quality inspection environments. The extension rod design allows the gauge to reach into bores and internal features, with a maximum extension rod length of 6 inches and a gauge depth of 97.00 mm. The 1.6000-inch setting ring diameter provides a reference standard for zeroing and verification. It is appropriate for any application requiring accurate internal dimensional measurement in the 40.00 to 50.00 mm range.

Installation Notes

Installation and setup should be performed by a qualified metrology technician or machinist familiar with precision measuring instruments. Before use, zero the instrument against the included or appropriate setting ring and verify calibration. Keep the measuring faces clean and free of debris to prevent measurement error. Store the instrument in its protective case when not in use to protect the carbide faces and electronics.
