Spi CMS220519043 Electronic Depth Micrometer 6 Inch

Product Description

The SPI CMS220519043 is a digital depth micrometer designed for precise depth measurement in machining, tooling, and metrology applications. It measures from 0 to 6.00 inches using a set of six interchangeable flat-end rods, giving technicians full range coverage without switching instruments. The stainless steel measuring faces resist wear, and the IP65 water resistance rating protects the electronics from coolant and cutting fluid splash common in shop environments. A ratchet thimble provides consistent measuring force, while the rotating spindle and selector-knob lock nut allow quick depth readings with repeatable results. The instrument ships with a lithium CR2032 battery installed and is calibrated to ASME B89.1.13.

This depth micrometer is suited for use in precision manufacturing, machine shops, tool and die operations, and quality control inspection. It is appropriate for measuring bore depths, step heights, slot depths, and shoulder distances on machined components. The 2.5-inch flat base provides stable seating across a range of workpiece surfaces. The built-in data output port allows integration with SPC data-collection systems for in-process documentation.

Key Features

Compatibility

Designed as an OEM-style precision depth measurement instrument compatible with standard flat-base depth micrometer rod sets and data output interfaces common to metrology and quality inspection workflows.

Installation Notes

Depth micrometers should be handled and stored by qualified metrology or inspection personnel following shop calibration procedures. Before use, verify the instrument is zeroed with the base seated flat on a reference surface. Keep the measuring faces and rod mating surfaces clean and free of chips or debris before rod changes to avoid measurement error. Periodic recalibration per ASME B89.1.13 guidelines is recommended to maintain traceability.
