Mitutoyo 167-165 Micrometer Calibration Standard Bar 25 Inch

The Mitutoyo 167-165 is a precision micrometer calibration standard bar designed for accurate zero-point setting and verification of outside micrometers. This 25-inch standard bar features a 0.47-inch diameter and provides a reliable reference surface for ensuring micrometer accuracy across extended measurement ranges.

Key Features:

• 25-inch length calibration standard for large-capacity outside micrometers
• 0.47-inch diameter cylindrical form
• Flat and precision-lapped measuring faces for accurate reference surfaces
• Heat-insulating handle prevents thermal expansion from body temperature transfer
• Hardened and stabilized steel construction for dimensional stability
• Essential tool for maintaining micrometer accuracy and calibration

This standard bar is an indispensable tool for quality control professionals, machinists, and metrology labs who require verification of micrometer accuracy at extended lengths. The insulated handle ensures handling does not affect the dimensional accuracy of the standard, while the precision-lapped surfaces provide reliable reference points for calibration procedures.
