Spi MS160712007 Micrometer Calibration Standard 7 in Flat

Product Description

The SPI MS160712007 is a flat end micrometer calibration standard designed to verify and maintain the accuracy of outside micrometers used in precision measurement applications. Measuring 7 inches in length, this calibration rod delivers accuracy up to 0.0002 inches, making it suitable for quality control environments where tight tolerances are critical. The included heat insulating handle minimizes thermal transfer from the technician's hand to the standard, which helps prevent measurement drift caused by thermal expansion. This tool is used by metrology technicians, machinists, and quality assurance personnel in manufacturing and inspection settings.

This calibration standard is intended for use with outside micrometers in precision measurement and inspection workflows. It is well suited for calibration benches, tool cribs, and quality labs where micrometers must be checked against a known reference before use. The flat end geometry makes it straightforward to seat against the micrometer anvil and spindle faces. The 7-inch length targets mid-range micrometer sets commonly used in production and maintenance environments.

Key Features

• Accuracy up to 0.0002 inches for reliable micrometer verification
• 7-inch length covers mid-range outside micrometer applications
• Flat end geometry for consistent, repeatable anvil contact
• Includes heat insulating handle to reduce thermal expansion error
• Factory calibrated for immediate use as a reference standard

Compatibility

Designed for use with outside micrometers as a reference calibration standard. Specific compatible micrometer models or system families are not identified in available product data.

Installation Notes

This calibration standard is handled by metrology technicians and quality control personnel rather than installed in a system. Store the standard in its protective case when not in use to prevent damage to the reference surfaces. Always allow the standard and the micrometer being checked to stabilize at the same ambient temperature before taking measurements. Handle the rod by the insulating grip only to avoid introducing thermal error into the calibration process.
