Spi MS170227015 Electronic Outside Micrometer 5 in IP54

Product Description

The SPI MS170227015 is an electronic outside micrometer designed for high-precision dimensional measurement in machining, toolmaking, and quality control environments. It measures up to 5 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 carbide-tipped measuring face resists wear during repeated use on hardened or abrasive workpieces. An IP54 rating provides protection against dust ingress and splash water, supporting use in typical shop floor conditions. A friction thimble delivers consistent measuring force to reduce operator-induced variation. This instrument is intended for use by machinists, metrologists, and precision measurement technicians.

The MS170227015 is suited for outside diameter and thickness measurements in manufacturing, inspection, and tool-and-die settings. It supports both absolute and incremental measuring modes, allowing the operator to zero at any position and track relative changes without resetting to a fixed reference. The instrument comes factory calibrated with NIST traceability certification included, meeting common requirements for documented quality systems. Batteries are included for immediate use out of the case.

Key Features

• Resolution of 0.000050 inches for high-precision measurement tasks
• Accuracy of 0.000200 inches across the measuring range
• Carbide-tipped measuring face for extended durability on hardened workpieces
• IP54-rated housing resists dust and splash in shop floor environments
• Supports absolute and incremental measuring modes
• NIST traceability certification included for quality system compliance
• Rotating spindle with friction thimble for consistent and repeatable feel

Compatibility

Designed as a standard outside micrometer for general precision measurement applications requiring a 0 to 5 inch measuring range.

Installation Notes

Outside micrometers require no installation but should be handled and stored according to standard metrology practices. Before use, verify the zero reference and inspect measuring faces for wear or contamination. Keep the instrument away from excessive heat, magnetic fields, and cutting fluids beyond the IP54 rating. Battery replacement uses an LR44 cell; open the battery compartment only when the instrument is dry and away from contaminating environments.
