INSIZE precision gauge block 50 mm class 1

INSIZE precision gauge block 50 mm class 1 provides a stable and accurate 50 mm reference length for dimensional measurement and calibration tasks. Manufactured by INSIZE for use in metrology, this solid gauge block is intended for setting and verifying the accuracy of calipers, micrometers, indicators and measuring machines in inspection, workshop and laboratory environments where traceable gauge standards are required.

Advantages

The gauge block delivers a reliable reference length with class 1 accuracy, ensuring repeatable results during calibration and comparative measurements. Its solid construction offers dimensional stability and resistance to everyday handling in industrial and laboratory conditions. The simple geometry and smooth surfaces facilitate easy wringing and secure stacking when building compound lengths.

Suitable for

• Calibration of calipers and micrometers
• Verification of height gauges and dial indicators
• Establishing reference lengths for CMMs and bench measuring machines
• Metrology labs, inspection benches and quality control stations

Key specifications

• Nominal length: 50 mm
• Accuracy class: Class 1
• Material: hardened and stabilized steel
• Surface finish: precision-ground and lapped for wringing
• Shape: rectangular precision block with parallel faces

How to use

Before use, ensure the gauge block and the measuring tool are clean and at a stable temperature close to the working environment. For single-length calibration, wring or place the block on the measuring instrument and allow the assembly to thermally stabilize. For compound lengths, carefully wring multiple blocks together to form the required nominal dimension. Use consistent handling techniques to avoid contamination or nicks on the reference faces, and follow your laboratory's calibration and traceability procedures when recording measurements.

Usage recommendations

Store the gauge block in a protective case when not in use, keep it free of oils and debris, and handle it with clean gloves or with a cloth to minimize fingerprints. Periodically check the block against higher-accuracy standards and schedule recalibration according to your quality system to maintain traceability and measurement confidence.
