Spi CMS150410008 Electronic Outside Micrometer 6 in IP65

Product Description

The SPI CMS150410008 is an electronic outside micrometer designed for high-precision dimensional measurement in machining, manufacturing, and metrology applications. It measures up to 6.0000 inches with a resolution of 0.000050 inches and an accuracy of 0.000200 inches, making it suitable for tight-tolerance work. The measuring faces are solid carbide for long-term durability and wear resistance. The unit carries an IP65 rating for protection against dust and coolant splash, and it ships calibrated with a NIST-traceable short-form certificate of calibration. Intended for use by machinists, quality control technicians, and tool and die professionals.

This micrometer is suited for precision outside diameter and thickness measurements in machine shops, production floors, and inspection environments where repeatable, verifiable readings are required. The electronic readout eliminates interpolation error common with analog thimble reading. The double ratchet friction thimble ensures consistent measuring force across repeated measurements. Batteries are included, and the instrument features automatic shut-off to preserve battery life during extended shop use.

Key Features

• Resolution of 0.000050 inches for high-precision dimensional measurement
• Accuracy of 0.000200 inches across the full measurement range
• Solid carbide measuring faces resist wear on hardened and abrasive workpieces
• IP65-rated housing protects against dust ingress and low-pressure coolant spray
• NIST-traceable calibration certificate included for quality and compliance documentation
• Automatic shut-off and CR2032 battery included for immediate field use
• Rotating spindle with double ratchet friction thimble for repeatable contact force

Compatibility

Designed as an OEM-style electronic outside micrometer for general precision measurement applications requiring a 0 to 6.0000 inch range with digital readout and NIST traceability.

Installation Notes

This instrument requires no installation in the traditional sense but should be handled and stored per standard metrology practices. Before use, verify the zero calibration at the reference anvil and confirm the certificate of calibration is on file for any regulated or audited quality system. Avoid dropping or impacting the measuring faces, and store in the provided case when not in use to protect the carbide faces and electronic components. Battery replacement uses a standard CR2032 cell.
