Spi CMS220519049 Electronic Inside Micrometer 10-12mm

Product Description

The SPI CMS220519049 is an electronic inside micrometer designed for precise internal bore and hole measurements in the 10.00 to 12.00 mm range. It features a ratchet stop thimble for consistent measuring force and alloy steel measuring faces for durability and accuracy. The instrument delivers accuracy of plus or minus 0.00010 inches, making it suitable for high-tolerance machining and inspection work. It includes data output capability for integration with SPC systems or data logging setups. A lithium CR2032 battery is included. This tool is used by machinists, toolroom technicians, and quality control inspectors working in precision manufacturing environments.

The CMS220519049 is suited for internal measurement tasks where small bore diameters require tight tolerances. With a gauge depth of 53.50 mm and a maximum extension rod length of 4 inches, it covers a practical range of internal measurement applications. The extension rod type design allows reach into confined bores. A setting ring with a 0.5000 inch diameter is included for calibration. The unit ships pre-calibrated, reducing setup time before first use. It is appropriate for use in machine shops, inspection departments, and manufacturing quality labs.

Compatibility

Designed as a standalone electronic inside micrometer for precision internal measurement applications. No specific system or machine compatibility was stated in the product data. Consult the manufacturer for extension rod and accessory compatibility with this model.

Installation Notes

Inside micrometers are typically handled and calibrated by qualified metrology or toolroom personnel. Before use, verify calibration against the included setting ring in a temperature-stable environment. Keep measuring faces clean and free of chips or coolant residue before taking measurements. Store in the provided case when not in use to protect the measuring faces and electronic components.
