Spi MS170309048 Electronic Outside Micrometer 1 in IP54

Product Description

The SPI MS170309048 is an electronic outside micrometer designed for precise external dimensional measurement in shop, toolroom, and field environments. It measures up to 1 inch with a resolution of 0.000050 inches and an accuracy of 0.000100 inches, making it suitable for tight-tolerance inspection work. The measuring faces are carbide-tipped for wear resistance during repeated use. A friction thimble provides consistent measuring force, reducing the risk of over-clamping the workpiece. The unit carries an IP54 rating, offering protection against dust ingress and splash water. It ships with NIST traceability certification and a battery installed, ready for immediate use on arrival.

This micrometer is used in precision machining, quality control, and metrology applications where accurate outside diameter or thickness readings are required. It suits both production floor and inspection room environments. The absolute and incremental measuring modes give technicians flexibility for both reference-point and comparative measurements. Machinists, quality inspectors, and toolroom technicians are the typical users. It is appropriate for measuring shafts, pins, stock thickness, and similar features where tolerances demand resolution beyond standard mechanical micrometers.

Compatibility

Designed as a standard outside micrometer for general-purpose precision measurement of external dimensions up to 1 inch.

Installation Notes

This instrument requires no permanent installation. Before use, verify the zero calibration per the manufacturer procedure with the spindle closed against the anvil. Keep the measuring faces clean and free of chips or coolant residue prior to each measurement. Store in the provided case when not in use to protect the carbide faces and electronic components.
