Spi CMS220519045 Electronic Depth Micrometer 12 in

Product Description

The SPI CMS220519045 is an electronic depth micrometer designed for precise depth measurement in machine shops, toolrooms, and manufacturing environments. It covers a measurement range of 0 to 12 inches using a set of 12 interchangeable flat-end rods, each swapped to extend range in 1-inch increments. The instrument delivers a resolution of 0.0001 inches and an accuracy of 0.0003 inches, making it suitable for demanding dimensional inspection work. The 4-inch flat base provides a stable, consistent reference surface. A ratchet thimble ensures repeatable seating force on each measurement. A data output port allows direct transfer of readings to a compatible SPC system or data logger. Licensed metrologists, quality inspectors, and precision machinists are the primary users.

This depth micrometer is built for both shop-floor and inspection-room use. The IP65 water resistance rating protects the electronics against coolant splash and dust ingress in active machining environments. The rotating spindle and selector-knob lock nut give the operator fine control during measurement and secure the reading before removal from the workpiece. The instrument ships calibrated to ASME B89.1.13 standards, ready for immediate use or direct entry into a calibration management program. It runs on a single 3V CR2032 lithium battery, included.

Compatibility

Designed as a general-purpose electronic depth micrometer compatible with standard flat-base depth measurement applications following ASME B89.1.13. No specific OEM system compatibility is stated for this part.

Installation Notes

Depth micrometers require no permanent installation. Before use, verify the base and rod contact faces are clean and free of chips or coolant residue. Insert the appropriate rod for the target depth range and confirm the lock nut is fully released before seating the base. When connecting to a data output system, follow the equipment manufacturer guidance for cable or interface compatibility to avoid damage to the data port.
