Spi MS160712009 Micrometer Calibration Standard 9 in

Product Description

The SPI MS160712009 is a flat-end micrometer calibration standard designed for verifying and setting the accuracy of outside micrometers. Measuring 9 inches in length, this calibration bar delivers accuracy up to 0.0002 inches, making it suitable for precision measurement applications in manufacturing, machining, and metrology environments. A heat insulating handle is included to prevent thermal expansion errors caused by hand contact, ensuring readings remain stable during calibration procedures. This type of standard is used by machinists, quality control technicians, and metrology professionals who require traceable, repeatable measurement verification.

This calibration standard is appropriate for use in shop-floor and lab environments where outside micrometers require routine verification or zero-setting. The 9-inch length accommodates larger-range micrometers commonly found in production machining and inspection settings. The flat end geometry is compatible with standard anvil-face micrometers. It ships pre-calibrated and is ready for immediate use upon receipt.

Key Features

• 9-inch overall length accommodates large-range outside micrometers
• Accuracy up to 0.0002 inches for reliable precision verification
• Flat end geometry compatible with standard micrometer anvil faces
• Includes heat insulating handle to minimize thermal expansion errors during use
• Ships pre-calibrated and ready for immediate deployment

Compatibility

Designed for use with outside micrometers requiring a flat-end calibration reference. Compatible with standard anvil-face micrometers across common measurement ranges covered by the 9-inch bar length.

Installation Notes

Calibration standards should be handled by the insulating handle to avoid heat transfer that can affect dimensional accuracy. Store the standard in a protective case away from direct sunlight and temperature extremes when not in use. Calibration verification should be performed in a thermally stable environment per applicable metrology procedures. Do not use the standard as a workholding or clamping device.
