Spi CMS220519046 Electronic Depth Micrometer 12 in

Product Description

The SPI CMS220519046 is an electronic depth micrometer designed for precise depth measurement in machining, tooling, and inspection applications. It covers a measurement range of 0 to 12 inches with a resolution of 0.0001 inches and an accuracy of 0.0003 inches. The unit features a 4-inch flat base, a ratchet thimble for consistent measuring force, and a rotating spindle. The stainless steel measuring faces resist wear and corrosion during regular shop use. A built-in data output port supports SPC data collection. Licensed metrology technicians, machinists, and quality control inspectors are the primary users of this instrument.

This depth micrometer is suited for measuring slot depths, counterbore depths, and step heights on precision machined components. The set includes 12 interchangeable flat-end rods, allowing coverage of the full 12-inch range in increments. The IP65 water resistance rating makes it appropriate for use in wet or coolant-exposed machine shop environments. The unit meets ASME B89.1.13 standards, making it acceptable for use in quality systems that require traceable calibration. It ships calibrated and battery-included, ready for immediate use on the shop floor or inspection bench.

Compatibility

Designed as a general-purpose electronic depth micrometer for use in precision machining, quality inspection, and toolroom environments where 0 to 12 inch depth measurements are required.

Installation Notes

This instrument is installed and operated by machinists, metrologists, or quality control technicians. Before use, verify the base seating surface and rod tips are clean and free of debris to ensure accurate readings. Select and attach the appropriate rod for the target measurement range, then lock with the selector knob after achieving a consistent ratchet-stop reading. Handle with care to avoid dropping, as impact can affect calibration; recalibrate per ASME B89.1.13 guidelines if the instrument is subjected to shock.
