Spi CMS220519037 Electronic Inside Micrometer 5-30mm

Product Description

The SPI CMS220519037 is an electronic inside micrometer designed for precise internal bore and hole measurements in machining, toolroom, and quality-control environments. It covers a measuring range of 5.00 to 30.00 mm with an accuracy of plus or minus 0.00020 inches, making it suitable for applications that demand tight dimensional tolerances. The measuring faces are made from solid carbide for durability and wear resistance. The instrument ships factory-calibrated and includes a data output port for integration with SPC systems or digital readout equipment. A single CR2032 lithium battery is included. Machinists, quality technicians, and tool-and-die professionals are the primary users.

This inside micrometer is suited for measuring the internal diameter of bores, rings, and cylindrical features across a 5.00 to 30.00 mm range. It fits comfortably into toolroom, inspection department, and production-floor workflows where electronic readout and data logging are standard practice. The ratchet rod and ratchet thimble mechanism provides consistent measuring force, which is important for repeatable readings on precision-tolerance work. A setting ring with a decimal inch diameter of 0.2000 inches is referenced for calibration verification. The unit arrives in a protective wooden storage box.

Compatibility

Designed as a standalone precision measuring instrument for general toolroom and inspection use across a 5.00 to 30.00 mm internal measurement range. No specific machine or system compatibility is stated by the manufacturer for this instrument.

Installation Notes

This instrument does not require installation, but proper handling procedures apply. Store the micrometer in its included wooden box when not in use and avoid contact with cutting fluids or abrasive surfaces that could damage the carbide measuring faces. Verify calibration against the included setting ring before use and after any drop or impact. Battery replacement uses a standard CR2032 lithium cell; follow the manufacturer guidelines for battery access to avoid damage to the housing or data port.
