Mitutoyo 167-148 Flat End Micrometer Standard 8 in

Product Description

The MITUTOYO 167-148 is a flat end micrometer calibration standard used to verify and maintain the accuracy of outside micrometers. Measuring 8 inches in length, this calibration bar delivers accuracy to 0.00015 inches, making it suitable for precision metrology applications in machine shops, manufacturing facilities, and calibration labs. The bar ships calibrated and ready for use. A heat insulating handle is included to prevent thermal expansion from hand contact, which can affect measurement readings at this level of precision. Calibration technicians and quality control personnel are the primary users of this tool.

This standard is designed for use with outside micrometers requiring an 8-inch reference. It is appropriate for production floor verification routines, periodic instrument calibration checks, and quality assurance workflows in environments where dimensional accuracy is critical. The included heat insulating handle allows the technician to hold the standard without introducing temperature-related dimensional changes during the calibration process.

Key Features

• 8-inch length provides a full-range reference for outside micrometers with matching capacity
• Accuracy to 0.00015 inches for high-precision verification work
• Shipped calibrated and ready for immediate use
• Includes heat insulating handle to minimize thermal expansion from handling
• Flat end design for consistent contact with micrometer anvil and spindle

Compatibility

Designed for use with outside micrometers requiring an 8-inch calibration reference standard.

Installation Notes

This calibration standard is handled by calibration technicians and quality control personnel, not installed in a system. Always allow the standard to thermally stabilize in the measurement environment before use. Handle only by the heat insulating handle to prevent body heat from affecting the bar length. Store in the provided case when not in use to protect the reference surfaces.
