Spi MS160712010 Micrometer Calibration Standard 10 in

Product Description

The SPI MS160712010 is a flat-end micrometer calibration standard designed for verifying and calibrating outside micrometers in precision measurement applications. At 10 inches in length, it provides a reference gauge for confirming micrometer accuracy to within 0.0002 inches. The unit is factory calibrated and ships ready for use. A heat-insulating handle is included to prevent thermal expansion from affecting measurement results during handling, which is a critical detail in high-accuracy metrology work. Machinists, quality control technicians, and tool room professionals rely on calibration standards like this one to maintain measurement traceability and instrument compliance.

This calibration standard is suited for use in machine shops, manufacturing facilities, inspection rooms, and tool cribs where micrometer accuracy must be verified on a regular basis. The flat end configuration is compatible with standard outside micrometer anvil faces. The included heat-insulating handle allows safe handling during calibration procedures without introducing dimensional error from body heat transfer. This type of standard is typically used as part of a scheduled gage calibration program or when an instrument has been dropped or serviced.

Key Features

• 10-inch length provides a long-range reference for outside micrometer calibration
• Accuracy up to 0.0002 inches for high-precision verification work
• Flat end shape compatible with standard micrometer anvil faces
• Factory calibrated and ready for immediate use out of the box
• Includes heat-insulating handle to prevent thermal growth during handling
• Lightweight at 0.5 pounds for easy bench use and storage

Compatibility

Designed for use with outside micrometers requiring a flat-end calibration reference. Suitable for standard micrometer calibration procedures across a range of instrument brands and styles.

Installation Notes

This is a calibration reference standard, not an installed component. Handle only by the heat-insulating handle to avoid thermal expansion effects that could introduce error. Store in a protective case away from temperature extremes, moisture, and contact with abrasive surfaces. Calibration procedures should follow applicable metrology standards and be performed by qualified personnel.
