Spi MS160712005 Micrometer Calibration Standard 5 in

Product Description

The SPI MS160712005 is a flat end micrometer calibration standard used to verify and set the accuracy of outside micrometers. Measuring 5 inches in maximum length, this calibration bar delivers accuracy up to 0.00016 inches, making it suitable for precision measurement environments where tight tolerances are critical. The standard is factory calibrated and includes a heat insulating handle to prevent thermal expansion caused by hand contact during use. It is the type of tool found on the bench of any machinist, metrologist, or quality control technician who relies on micrometer accuracy for production or inspection work.

This calibration standard is designed for use with standard outside micrometers in machine shops, manufacturing facilities, and quality assurance labs. It is appropriate for both production floor use and metrology room settings where periodic micrometer verification is required. The 5 inch length accommodates larger-range micrometers and serves as a reference point when checking calibration across the full measuring range of the instrument.

Key Features

• Maximum length of 5 inches for use with larger-range outside micrometers
• Accuracy up to 0.00016 inches for tight-tolerance verification work
• Flat end geometry for consistent, repeatable contact with micrometer anvils
• Factory calibrated and ready for immediate use as a reference standard
• Includes heat insulating handle to minimize thermal error during handling

Compatibility

Designed for use with outside micrometers. Consult the manufacturer documentation to confirm range compatibility with your specific micrometer model before use.

Installation Notes

This calibration standard requires no installation. Qualified technicians or metrologists should handle calibration checks in accordance with their facility measurement system requirements. Always hold the standard by the heat insulating handle to prevent body heat from affecting the reference dimension. Store the standard in a protective case away from moisture and temperature extremes when not in use.
