For calibration laboratories, quality control departments, and precision manufacturing facilities, Mitutoyo Gauge Blocks deliver the absolute accuracy required for critical measurement applications. These master length standards form the foundation of reliable dimensional measurement systems worldwide.

Precision Engineering for Demanding Applications

Mitutoyo Gauge Blocks are available in multiple accuracy grades to meet specific needs:

• Grade 00: Laboratory master standards

• Grade 0: High-precision calibration

• Grade 1/2: Workshop and toolroom use

Each block undergoes precision lapping to achieve exceptional surface finish, flatness, and parallelism. The renowned wringing capability allows blocks to combine through molecular adhesion, creating custom dimensions with minimal uncertainty.

Key Benefits:

• Certified Traceability: Each set includes calibration certificate traceable to NIST

• Exceptional Durability: High-carbon steel construction resists wear and corrosion

• Temperature-Stable: Low coefficient of thermal expansion ensures reliability

• Multiple Configurations: Available in 81-, 36-, and 18-piece sets

Common Applications:

• Calibrating micrometers, calipers, and dial indicators

• Setting sine bars and optical comparators

• Verifying CMM and vision system performance

• Precision machining setup and inspection

Why Professionals Choose Mitutoyo: Mitutoyo's commitment to metrology excellence ensures each gauge block maintains dimensional stability over time. The superior surface finish and wringing characteristics provide reliable performance that cheaper alternatives cannot match.

Upgrade Your Measurement Capabilities: Ensure your quality system rests on the most reliable foundation. Mitutoyo Gauge Blocks provide the accuracy needed for ISO 9001 and IATF 16949 compliance.

• Precision and accuracy demanded by the automated assembly and inspection markets, are guaranteed.
• Sliding durability of more than 50 million times*, with protection level of IP67G. Highly oil-resistant material is used in the rubber cap and cable sheath, so it can be used even in harsh environments.
• Reference point signal output functions are featured throughout this series. When incorporating into a device, the master setting value is easy to set and is retained after shutdown. Re-setting the origin is possible when there are problems such as excessive speed, ensuring excellent reliability.
• Data can be output through an industrial interface (CC-Link) by linking a compact counter (EJ counter) with an interface unit. Constant data monitoring and positional management are performed. A USB interface is also provided for easy connection with a computer.
