Spi CMS220519038 Electronic Inside Micrometer 25-50mm

Product Description

The SPI CMS220519038 is an electronic inside micrometer designed for precision internal diameter measurement across a range of 25.00 to 50.00 mm. Built for dimensional inspection work, it delivers accuracy to plus or minus 0.00020 inches, making it suitable for tight-tolerance bore and hole measurement in machining, manufacturing, and quality-control environments. The measuring faces are solid carbide for durability and wear resistance. A ratchet thimble and ratchet rod provide consistent measuring pressure, and the instrument supports data output for integration with SPC systems or digital logging setups. A calibrated setting ring with a 1.0000-inch decimal diameter is included for on-the-bench verification.

This inside micrometer is intended for use in precision measurement applications where electronic readout and data output capability are required. Typical users include machinists, quality-control technicians, and tool-and-die professionals working in industrial or production environments. The unit ships in a wooden box suitable for storage and bench-top use. It arrives calibrated and battery-ready with a lithium CR2032 cell included.

Compatibility

Designed as a standalone electronic inside micrometer for precision internal diameter measurement in the 25.00 to 50.00 mm range. No specific system or machine compatibility is stated in the product data.

Installation Notes

This instrument is a handheld precision measuring tool and does not require mechanical installation. Before use, verify calibration using the included setting ring and ensure the measuring faces are clean and free of debris. Handle solid carbide measuring faces with care to avoid chipping. Replace the CR2032 lithium battery when the low-battery indicator activates to maintain measurement integrity.
