Mitutoyo 167-149 Micrometer Calibration Standard 9 in

Product Description

The MITUTOYO 167-149 is a flat end micrometer calibration standard designed for use with outside micrometers in precision measurement applications. This gauge bar measures 9 inches in length and delivers accuracy up to 0.0002 inches, making it a reliable reference tool for verifying and calibrating outside micrometer instruments. The unit ships factory-calibrated and includes a heat insulating handle to prevent thermal expansion errors during use. Licensed metrologists, calibration technicians, and quality control professionals rely on this type of standard to maintain traceable measurement accuracy in shop, lab, and field environments.

This calibration standard is suited for precision metrology environments where outside micrometer accuracy must be verified or documented. Typical applications include calibration labs, incoming inspection stations, tool cribs, and production floor QC checks. The 9-inch length makes it appropriate for calibrating larger-range outside micrometers. The included heat insulating handle allows the user to hold the standard without transferring body heat to the bar, which would otherwise introduce dimensional error into the calibration process.

Key Features

• 9-inch length for calibrating large-range outside micrometers
• Accuracy up to 0.0002 inches for precise reference measurement
• Factory-calibrated for immediate use out of the box
• Includes heat insulating handle to minimize thermal expansion error
• Flat end design compatible with outside micrometer anvil and spindle faces

Compatibility

Designed for use with outside micrometers requiring a 9-inch flat end calibration reference standard. No specific model compatibility data was provided in the product input.

Installation Notes

Calibration standards of this type are handled and used by calibration technicians following applicable metrology procedures and traceability requirements. Always hold the standard by the heat insulating handle to avoid introducing thermal error. Store the bar in its protective case when not in use to prevent surface damage that could affect reference accuracy. Do not use this standard as a structural gauge block or subject it to impact loads.
