The MITUTOYO 167-141 is a precision micrometer calibration standard designed to verify and set the accuracy of outside micrometers. Measuring 1 inch in length with a flat end configuration, this gauge block-style reference standard delivers an accuracy of 0.000005 inches, making it suitable for high-tolerance metrology work in machine shops, tool rooms, and calibration labs. The unit ships calibrated and includes a heat insulating handle to prevent thermal expansion errors caused by hand contact during use. Calibration technicians and precision machinists rely on this type of standard to maintain traceability and measurement integrity.
This calibration standard is intended for use with outside micrometers in settings where dimensional accuracy must be confirmed before measurement tasks or at regular calibration intervals. It is well suited to production environments, quality control stations, and tool crib operations where outside micrometers are in frequent service. The flat end geometry ensures consistent, repeatable contact against the micrometer anvil and spindle faces. The included heat insulating handle is a critical feature for maintaining the dimensional integrity of the standard throughout the calibration process.
Designed for use with outside micrometers as an OEM-style calibration and verification reference standard.
Calibration standards are handled and used by calibration technicians and precision measurement personnel, not installed in a traditional sense. Always allow the standard to thermally stabilize to ambient temperature before use. Hold the standard exclusively by the heat insulating handle to prevent body heat from altering its dimensional accuracy. Store in its protective case when not in use to prevent surface damage to the reference faces.
