Spi CMS150410006 Electronic Outside Micrometer 4 in IP65

Product Description

The SPI CMS150410006 is an electronic outside micrometer designed for precise dimensional measurement in shop, inspection, and field environments. It measures up to 4 inches with a resolution of 0.000050 inches and an accuracy of 0.000200 inches, making it suitable for applications that demand tight tolerances. The solid carbide measuring faces resist wear during repeated use. An IP65 rating protects the instrument against dust ingress and low-pressure water jets, allowing use in wet or contaminated work areas. A ratchet friction thimble provides consistent measuring force across readings. Calibrated to NIST-traceable standards, this micrometer ships with a short-form certificate of calibration. Licensed metrologists, quality technicians, and precision machinists are the primary users.

This micrometer suits dimensional inspection work in manufacturing, machining, and quality control settings. The 4-inch maximum measurement range covers a broad range of shaft, bore, and part thickness measurements common in production and maintenance environments. The IP65 rating makes it a practical choice for use on the shop floor where coolant or debris may be present. Automatic shut-off helps preserve battery life during intermittent use. The included CR2032 battery allows immediate use out of the box.

Key Features

Compatibility

Designed as a general-purpose electronic outside micrometer for use with workpieces requiring measurement in the 3-inch to 4-inch range, consistent with standard inch-series outside micrometer applications.

Installation Notes

No installation is required for handheld measuring instruments. Store the micrometer with the measuring faces slightly open to prevent face contact during transport and storage. Keep the instrument away from strong magnetic fields and extreme temperature changes, which can affect electronic accuracy. Calibration should be verified periodically per your facility quality plan and applicable standards.
