Mitutoyo 167-164 Micrometer Calibration Standard 24 in

Product Description

The MITUTOYO 167-164 is a flat end micrometer calibration standard designed for verifying and calibrating outside micrometers. At 24 inches in maximum length and rated to an accuracy of 0.0003 inches, this calibration bar gives precision measurement professionals a reliable reference for confirming micrometer performance. The unit ships calibrated and includes a heat insulating handle, allowing technicians to hold the standard without transferring body heat that could affect dimensional accuracy during measurement. Calibration standards of this type are used in metrology labs, tool rooms, and quality control environments where traceable measurement verification is required.

This standard is suited for use in industrial, manufacturing, and trade settings where outside micrometers must be regularly verified against a known reference. The 24-inch length accommodates larger-range micrometer calibration tasks. The included heat insulating handle is a practical feature for bench use, preventing thermal expansion from hand contact from introducing error into calibration readings. Licensed metrologists, tool and die technicians, and QC inspectors are the primary users of this type of calibration equipment.

Key Features

• 24-inch maximum length covers larger outside micrometer calibration ranges
• Accuracy rated to 0.0003 inches for precise reference measurement
• Ships calibrated for immediate use as a reference standard
• Includes heat insulating handle to minimize thermal expansion error during use
• Flat end design for consistent contact with micrometer anvil and spindle faces

Compatibility

Designed for use with outside micrometers as a calibration and verification reference standard. Specific compatible micrometer models or system families were not identified in available product data.

Installation Notes

Calibration standards should be handled using the included heat insulating handle to prevent body heat from affecting dimensional accuracy. Store the standard in a controlled temperature environment when not in use. Calibration procedures should follow applicable metrology standards and laboratory protocols. Verification of outside micrometers using this standard should be performed by qualified personnel familiar with precision measurement practices.
