Mitutoyo 167-156 Micrometer Calibration Standard Bar 16 Inch

The Mitutoyo 167-156 is a precision 16-inch micrometer calibration standard bar designed for accurate zero-point setting and calibration verification of outside micrometers. This essential metrology tool features a 0.37-inch diameter and provides a reliable reference standard for maintaining measurement accuracy in quality control and inspection applications.

Key Features:

• 16-inch length standard bar for calibrating large outside micrometers
• Flat and lapped measuring faces ensure precise contact and accurate calibration
• Heat-insulating handle prevents thermal expansion from body heat during handling
• 0.37-inch diameter provides sturdy construction and stability
• Manufactured to Mitutoyo's strict quality standards for measurement reliability

This calibration standard is an indispensable tool for machinists, quality inspectors, and metrologists who require traceable accuracy for their micrometer measurements. The heat-insulating handle is a critical feature that maintains dimensional stability by isolating the measuring bar from the warmth of the operator's hands, ensuring consistent and repeatable calibration results.
