Mitutoyo 167-912 Micrometer Calibration Standard Set

Product Description

The MITUTOYO 167-912 is a 5-piece micrometer calibration standard set designed to verify and maintain the accuracy of outside micrometers. Each steel gauge rod is precision-ground to a specific length from 1 inch through 5 inches, providing a traceable reference at each common measurement increment. Accuracy is held to 0.000012 inches, making this set suitable for demanding shop and field calibration work. The set includes heat-insulating handles on each standard, allowing technicians to handle the rods without transferring body heat that could affect dimensional readings. A carrying case is included for organized storage and transport.

This calibration standard set is used in manufacturing, machine shops, and service environments where outside micrometer accuracy must be confirmed before or after use. Metrology technicians, quality control inspectors, and precision tradespeople rely on gauge rod sets like this one to detect spindle wear, anvil damage, or calibration drift in their measuring instruments. The 1-inch through 5-inch range covers the most common outside micrometer sizes in typical shop use.

Key Features

• Accuracy of 0.000012 inches for reliable traceable calibration reference
• 5-piece set covers 1 inch, 2 inches, 3 inches, 4 inches, and 5 inches
• Heat-insulating handles on each rod minimize thermal expansion from hand contact
• Calibrated from the factory for immediate use upon receipt
• Includes carrying case for secure storage and organized transport

Compatibility

Designed for use with outside micrometers. The 1-inch through 5-inch range corresponds to standard outside micrometer sizes commonly found in trade and industrial settings.

Installation Notes

Calibration standards are handled by metrology technicians and quality control personnel rather than installed in a system. Allow gauge rods to stabilize to ambient temperature before use, as thermal expansion can affect readings at this level of precision. Hold rods by the insulating handles only to avoid transferring body heat to the measuring surface. Store in the provided carrying case when not in use to prevent surface damage.
