Spi MS170227014 Electronic Outside Micrometer 6 Inch

Product Description

The SPI MS170227014 is an electronic outside micrometer designed for high-precision dimensional measurement in machining, manufacturing, and metrology applications. It measures up to 6 inches with a resolution of 0.000050 inches and an accuracy of 0.000200 inches. The carbide-tipped measuring face resists wear under repeated use on hardened workpieces. An IP54 rating provides protection against dust ingress and splashing water, making it suitable for use on the shop floor. A friction thimble delivers consistent measuring force to prevent over-tightening and protect measurement integrity. The unit supports both absolute and incremental measuring modes and ships with an NIST traceability certification included.

This micrometer is suited for precision trade work including toolmaking, machining, quality inspection, and fabrication environments. Machinists, metrologists, and quality control technicians working with shafts, pins, and other turned or milled components will find the electronic readout and dual measuring modes practical for both production and inspection tasks. The rotating spindle design aids in workpiece contact and repeatability across measurements.

Key Features

• Measures from 125 mm minimum to 6 inches maximum
• Resolution of 0.000050 inches for fine dimensional work
• Carbide-tipped measuring face for extended wear resistance
• IP54 rated for dust and splash resistance in shop environments
• Supports absolute and incremental measuring modes
• NIST traceability certification included for calibration records
• Battery included — LR44 cell, ready to use out of the box

Compatibility

Designed as a standard outside micrometer for general-purpose precision measurement of external dimensions on round and flat workpieces in machining and inspection applications.

Installation Notes

No installation is required for handheld measuring instruments. Prior to first use, verify calibration against the included NIST traceability documentation and set the zero reference point per standard micrometer procedure. Store the instrument in its case when not in use to protect the measuring faces and electronic components. Battery replacement uses a standard LR44 cell.
