Spi CMS160622004 Electronic Outside Micrometer Set 4 Piece

Product Description

The SPI CMS160622004 is a 4-piece electronic outside micrometer set covering a measurement range of 0 to 4 inches (0 to 100 mm). Each micrometer in the set features a 0.001 mm digital resolution and an accuracy rating of 0.003 mm, making this set well-suited for precision dimensional inspection work in machining, manufacturing, and metrology applications. The carbide-tipped measuring faces resist wear over repeated use, and the friction thimble provides consistent measuring force to reduce operator-to-operator variation. The IP54 ingress protection rating means the instruments are protected against dust ingress and splashing water, supporting use in typical shop floor environments. Each unit is factory calibrated and ships with a short-form certificate of calibration.

This micrometer set is intended for machinists, quality control technicians, tool and die makers, and precision measurement professionals who need outside diameter and thickness measurement capability across the full 0 to 4 inch range without swapping instruments. The set is suited for both production floor inspection and toolroom use. Battery-powered digital readout eliminates manual interpolation of vernier graduations, reducing read error on critical dimensions. The included case organizes all four micrometers for storage and transport between workstations or job sites.

Compatibility

Designed as a standalone 4-piece electronic outside micrometer set for general precision measurement applications requiring 0 to 4 inch outside diameter and thickness capability.

Installation Notes

Outside micrometers are calibrated instruments and should be handled and stored according to standard metrology practices. Before use, verify the zero setting of each micrometer against the included standard and adjust as needed. Avoid dropping or impacting the measuring faces, as this can affect calibration. Store the instruments in the provided case when not in use to protect the measuring faces and electronic components.
