The SPI CMS220519016 is an electronic blade micrometer designed for precision measurement in tight grooves, keyways, and narrow slots where standard anvil micrometers cannot reach. It measures up to 1 inch with an accuracy of plus or minus 0.0001 inches and a graduation of 0.0001 inches. The ratchet thimble ensures consistent measuring force across repeated measurements, reducing operator-to-operator variation. The digital readout eliminates interpolation errors and supports data output for integration with statistical process control systems. The carbide anvil and blade provide durability in shop environments. This tool is used by machinists, quality control technicians, and tool-and-die professionals who require reliable sub-thousandth measurements on narrow features.
The CMS220519016 is suited for inspection and production work involving narrow-profile features such as keyways, slots, splines, and recessed grooves. The 0.75 mm blade thickness and 6.50 mm blade depth allow access to confined measurement zones that standard outside micrometers cannot accommodate. It is calibrated to ASME 89.1.13 standards, making it appropriate for controlled inspection environments and quality systems requiring traceable measurement tools. The unit ships with a protective plastic storage box and a CR2032 lithium battery installed.
Designed as an OEM-style precision measurement tool compatible with standard SPC data collection systems that accept micrometer data output signals; no specific machine or system compatibility data was provided in the product input.
This micrometer is a handheld precision measuring instrument and does not require mechanical installation. Before use, zero the instrument with the blade faces clean and fully closed. Store in the included plastic box away from heat, moisture, and magnetic fields that could affect calibration. Battery replacement uses a standard CR2032 lithium cell; open the battery compartment carefully to avoid damaging the electronics housing.
