Spi CMS150410007 Electronic Outside Micrometer 5 in IP65

Product Description

The SPI CMS150410007 is an electronic outside micrometer designed for precision dimensional measurement in professional machining, manufacturing, and metrology environments. It measures from 4 inches to 5 inches maximum, delivering a resolution of 0.000050 inches and an accuracy of 0.000200 inches. The solid carbide measuring faces resist wear on hardened workpieces, and the IP65 rating protects the electronics from coolant splash and dust ingress. A ratchet friction thimble ensures consistent measuring force on every reading. This tool is calibrated to NIST-traceable standards and ships with a short-form certificate of calibration, making it ready for use in quality-controlled production environments.

This micrometer is suited for precision shops, tool rooms, inspection departments, and field metrology work where outside diameter or thickness measurements in the 4-inch to 5-inch range are required. The digital readout eliminates interpolation error common with vernier scales. The automatic shut-off feature conserves battery life during intermittent use. It is appropriate for machinists, quality technicians, tool-and-die makers, and maintenance professionals who require traceable, high-accuracy outside measurements on shafts, flanges, and similar components.

• Solid carbide measuring faces for extended service life on hardened materials
• IP65-rated housing resists coolant splash and fine particle ingress
• Ratchet friction thimble provides repeatable, consistent measuring force
• NIST-traceable calibration certificate included for quality system compliance
• Automatic shut-off and CR2032 battery included for immediate deployment

Compatibility

Designed as a direct-use electronic outside micrometer for outside diameter and thickness measurement applications requiring a 4-inch to 5-inch range with digital readout capability.

Installation Notes

No installation is required for this handheld precision measuring instrument. Before use, verify calibration status using the included short-form certificate and confirm the measuring faces are clean and free of debris. Protect the tool from impact and store it in its case when not in use to preserve face integrity and electronic function. Battery replacement uses a standard CR2032 cell.
