Mitutoyo Micrometer Standard Bar Calibration Tool

The Mitutoyo Micrometer Standard Bar is a precision calibration tool, also called a micrometer setting standard or setting bar. It is used to check and set the zero point of outside micrometers so that your measurements stay accurate and repeatable in the shop, tool room, or inspection lab.

Key Features:

• Precision-ground reference standard for verifying and adjusting outside micrometers
• Built by Mitutoyo, a long-established maker of precision measuring instruments
• Gives a known, fixed length to check micrometer accuracy against
• Suited to routine calibration checks as part of a quality control routine
• Available in multiple lengths to match the range of your micrometers

Checking your micrometers against a reliable standard bar helps you catch wear or drift early, which supports consistent measurement quality in machining, fabrication, and engine building work.
