Spi CMS220519006 Electronic Outside Micrometer 5-6 in

Product Description

The SPI CMS220519006 is a digital outside micrometer designed for precision measurement in the 5 to 6 inch range. It features a carbide-tipped measuring face for long-term wear resistance and a ratchet thimble that delivers consistent, repeatable measuring pressure across readings. Accuracy is rated at plus or minus 0.00020 inches, making it suitable for close-tolerance inspection work in machining, fabrication, and maintenance environments. The unit carries an IP65 ingress protection rating, providing resistance to dust and low-pressure water spray. A lever-style lock nut secures the spindle at any measurement point.

This micrometer is used in precision measurement applications across manufacturing, industrial maintenance, and quality control settings. Its 5 to 6 inch measuring range targets larger-diameter workpieces such as shafts, bores, and machined components requiring tight dimensional verification. The digital readout reduces reading error and speeds up inspection workflows. It is appropriate for use by machinists, metrologists, maintenance technicians, and quality assurance personnel working to ASME B89.1.13 standards.

Compatibility

Designed as a standard outside micrometer for bench and field measurement use; compatible with workpieces requiring measurement in the 5 to 6 inch range where ASME B89.1.13 compliance is specified.

Installation Notes

This instrument is a handheld measuring tool and does not require installation. Prior to use, verify calibration status and clean both measuring faces with a lint-free cloth. Do not over-tighten the thimble against a workpiece; use the ratchet mechanism to achieve proper measuring force. Store in the supplied case when not in use to protect the measuring faces and electronics.
