Spi MS160712014 Micrometer Calibration Standard 14 in

Product Description

The SPI MS160712014 is a spherical end micrometer calibration standard designed to verify and maintain the accuracy of outside micrometers used in precision measurement applications. At 14 inches in overall length and accurate to 0.00025 inch, this calibration bar provides a reliable reference for technicians and quality control personnel who need to confirm micrometer readings before critical measurements. The included heat insulating handle minimizes thermal transfer from the user's hand, which helps prevent dimensional changes caused by body heat during calibration checks. Metrology technicians and tool room staff are the primary installers and users of this standard.

This calibration standard is suited for use in tool rooms, metrology labs, machine shops, and quality control environments where micrometer accuracy must be verified at regular intervals or after equipment is serviced. The spherical end design ensures consistent contact geometry with the micrometer anvil and spindle, reducing measurement variability during the calibration process. It is appropriate for environments requiring traceability and documented measurement assurance as part of a quality management system.

Key Features

• Accuracy to 0.00025 inch for precise micrometer verification
• Spherical end geometry provides repeatable, consistent contact during calibration
• 14 inches overall length accommodates a wide range of micrometer sizes
• Includes heat insulating handle to reduce thermal growth during use
• Pre-calibrated at the factory for immediate use out of the box

Compatibility

Designed for use with outside micrometers requiring a calibration reference standard. Specific compatible micrometer models are not listed in the available product data.

Installation Notes

This calibration standard does not require installation in the traditional sense but should be handled with care to avoid surface damage, which would affect accuracy. Always hold the standard by the heat insulating handle to prevent thermal expansion from body heat. Store the standard in its protective case when not in use and keep it away from moisture, abrasives, and extreme temperature changes. Calibration procedures should follow the facility's established metrology protocols and any applicable quality management standards.
