Calibration Gauge Block Set Mitutoyo 0.996 mm (model 611556-031)

Mitutoyo calibration gauge block with nominal thickness 0.996 mm is a precision reference plate designed for use in measurement and calibration tasks. Manufactured by Mitutoyo, this gauge block provides a stable thickness reference for setting standards, verifying instrument accuracy, and supporting dimensional inspection workflows. It is intended for environments where consistent, traceable thickness is required, such as metrology laboratories, quality control stations, and precision workshops.

Advantages

The gauge block offers high dimensional stability and a precisely finished surface that facilitates repeatable seating and measurement. Its nominal thickness of 0.996 mm is produced to tight tolerances, making it suitable as a reference for comparator checks, calibration of thickness gauges, and verification of micrometers and other length-measuring instruments. The product’s geometry and surface flatness support accurate optical and tactile measurement methods without introducing unnecessary variables into the measurement chain.

Suitable for

• Calibration of micrometers, calipers and thickness gauges
• Reference standard in metrology laboratories
• Dimensional inspection and quality control routines
• Instrument verification and comparator setups
• Workshop use where precise thickness reference is required

Key specifications

• Nominal thickness: 0.996 mm
• Type: calibration gauge block / reference plate
• Surface finish: precision ground and lapped for reliable seating
• Material: hardened and stabilized steel suitable for dimensional standards
• Intended application: precision thickness reference for calibration and measurement

How to use

Before use, ensure the gauge block and measuring instruments are clean and at the same ambient temperature to minimise thermal effects. Handle the block by its edges or with gloves to avoid contamination from skin oils. Place the gauge block on a stable, vibration-free surface or in the appropriate fixture for comparison. Use established calibration procedures when comparing or setting instruments, allowing instruments to stabilise against the block prior to taking measurements. Record measured values and environmental conditions as required by your quality system.

Usage recommendations

Store the gauge block in a protective case when not in use, keep it dry and avoid exposure to corrosive environments. Regularly inspect the surface for wear and contamination and include the block in periodic calibration schedules to maintain traceability and reliability.
