Spi CMS150410005 Electronic Outside Micrometer 2in IP65

Product Description

The SPI CMS150410005 is an electronic outside micrometer designed for precision dimensional measurement in machining, metrology, and quality control environments. It measures external dimensions up to 2 inches with a resolution of 0.000050 inches and an accuracy of 0.000200 inches, making it suitable for close-tolerance inspection work. The measuring faces are solid carbide for extended wear resistance. The ratchet friction thimble ensures consistent measuring pressure across repeated measurements. This instrument is rated IP65 for protection against dust ingress and low-pressure water jets, supporting use in typical shop floor conditions. It ships calibrated and includes a NIST-traceable short form certificate of calibration.

The CMS150410005 is used in precision machining shops, tool rooms, and quality inspection departments where tight tolerances must be verified on turned, ground, or milled components. It is appropriate for applications requiring sub-thousandth resolution, including aerospace, automotive, and general manufacturing. The included calibration certificate supports compliance documentation requirements. The automatic shut-off feature preserves battery life during intermittent use. A CR2032 battery is included. This micrometer suits machinists, metrologists, and QC inspectors working to close dimensional tolerances in production or inspection settings.

Key Features

• Resolution of 0.000050 inches for sub-thousandth measurement capability
• Accuracy of 0.000200 inches across the measurement range
• Solid carbide measuring faces resist wear on hardened workpieces
• IP65-rated housing provides protection from dust and water spray in shop environments
• Ratchet friction thimble delivers repeatable measuring force
• Ships calibrated with a NIST-traceable short form certificate of calibration
• Automatic shut-off extends CR2032 battery life

Compatibility

Designed as a standalone electronic outside micrometer for external dimensional measurement of workpieces up to 2 inches. Suitable for use with standard micrometer stands and fixtures that accept conventional outside micrometer frames.

Installation Notes

This instrument does not require installation but should be handled and stored according to standard metrology practices. Zero the micrometer with the spindle fully closed before use and verify with gauge blocks if traceability is required. Keep the measuring faces clean and free of chips or coolant residue before each measurement. Store in the provided case when not in use to protect the carbide faces and electronic components.
