Spi CMS220519044 Electronic Depth Micrometer 6 Inch

Product Description

The SPI CMS220519044 is an electronic depth micrometer designed for precise depth measurement in machining, toolmaking, and quality control applications. It measures from 0 to 6.00 inches using six interchangeable flat-end rods and features a digital readout with a resolution of 0.0001 inch and an accuracy of 0.0002 inch. The 2.5-inch flat base sits flush against reference surfaces for repeatable, stable readings. A ratchet thimble ensures consistent measuring pressure, and a selector-knob lock nut holds the reading in place. Data output capability allows integration with SPC systems. This instrument is used by machinists, metrologists, and quality technicians.

This depth micrometer is suited for shop-floor and inspection-room use in precision manufacturing environments. The IP65 water-resistance rating makes it appropriate for environments with coolant exposure or particulate contamination. The rotating spindle and flat-end rod design accommodate a wide range of bore, slot, and shoulder depth measurements. It ships with one CR2032 lithium battery installed and is calibrated to ASME B89.1.13 standards, making it ready for immediate use in certified inspection workflows.

Key Features

• Measurement range: 0 to 6.00 inches via 6 interchangeable flat-end rods
• Resolution of 0.0001 inch with accuracy of 0.0002 inch
• IP65-rated water and dust resistance for shop-floor durability
• Data output port for direct SPC or computer interface
• Ratchet thimble delivers consistent, repeatable measuring force
• Calibrated to ASME B89.1.13; includes lithium CR2032 battery

Compatibility

Designed as an OEM-style electronic depth micrometer compatible with standard flat-base depth measurement applications requiring a 2.5-inch base and interchangeable rod sets up to 6.00 inches.

Installation Notes

Electronic depth micrometers require no installation but should be handled and stored by calibrated instrument procedures. Before use, verify the base reference surface is clean and free of burrs or debris that could affect zero-setting accuracy. Lock the spindle using the selector-knob lock nut when transferring the instrument to a readout position. Battery replacement uses a standard 3V CR2032 cell; discharge the instrument of static before opening the battery compartment in sensitive environments.
