Mitutoyo 167-150 Flat End Micrometer Calibration Standard

Product Description

The MITUTOYO 167-150 is a flat end micrometer calibration standard designed for verifying and calibrating outside micrometers. At 10 inches in length, this reference bar delivers accuracy up to 0.0002 inches, making it a reliable tool for precision measurement verification in machine shops, metrology labs, and field service environments. The unit includes a heat insulating handle, which minimizes thermal transfer from the technician's hand to the bar, helping maintain dimensional stability during use. Calibration standards like this one are essential when technicians need traceable verification of micrometer performance before critical measurements.

This calibration standard is suited for use in industrial and precision trade settings where outside micrometer accuracy must be confirmed before production, inspection, or quality control work. It is appropriate for machinists, calibration technicians, and quality assurance personnel working with large-range outside micrometers that measure up to 10 inches. The included heat insulating handle makes it practical for bench use without the need for additional fixtures during routine calibration checks.

Key Features

• 10-inch reference length for calibrating large-range outside micrometers
• Accuracy up to 0.0002 inches for precise measurement verification
• Factory calibrated — ready for use as a traceable reference standard
• Includes heat insulating handle to minimize thermal expansion from hand contact
• Flat end design compatible with standard outside micrometer anvil and spindle faces

Compatibility

Designed for use with outside micrometers requiring a 10-inch calibration reference standard. Confirm micrometer range and anvil style before use to ensure proper fitment with this bar.

Installation Notes

Calibration standards should be handled by the insulating handle only to prevent body heat from affecting the bar's dimensions. Allow the standard to stabilize to ambient temperature before taking reference measurements. Calibration work should be performed by qualified metrology or calibration technicians following applicable standards and documented procedures. Store the standard in its case when not in use to protect the reference surfaces.
