Gauge Block Plate INSIZE 20 mm class 2 (4101-C20) with Certificate

The INSIZE Gauge Block Plate 20 mm class 2 (model 4101-C20) is a precision reference plate with a nominal thickness of 20 mm supplied with a calibration certificate. Designed for metrology laboratories and quality control environments, this flat, stable reference surface is intended for calibration, inspection and verification of measuring instruments, gauge blocks and fixtures. The plate provides a consistent thickness and surface for comparative measurements and for setting dimensional standards.

Advantages

The INSIZE 20 mm plate offers traceable calibration delivered with a certificate, ensuring documented accuracy for laboratory and production use. Its class 2 tolerance provides a balance between precision and cost for routine calibration and inspection tasks. The plate’s stable construction and uniform thickness reduce variability during comparative measurements and help maintain repeatability across measurement sessions.

Suitable for

• Calibration of comparator stands and height gauges
• Verification of gauge blocks and master measurements
• Setting reference planes for metrology fixtures
• Quality control checks in production and inspection stations

When it may not be suitable

This class 2 gauge block plate is not intended for applications that require the highest metrological accuracy where class 1 or higher-grade reference standards are mandatory. It may not be suitable where sub-micron flatness or the tightest dimensional tolerances are required for primary calibration standards.

Key specifications

• Nominal thickness: 20 mm
• Accuracy class: Class 2
• Surface: precision ground flat reference surface
• Included documentation: calibration certificate
• Typical use environment: metrology labs and quality control

How to use

Before use, ensure the plate and the instrument under test are clean and free of debris, oil or dust. Condition the plate and measuring equipment to the same ambient temperature to minimise thermal expansion effects. Place the gauge block plate on a stable, vibration-free surface; when comparing or calibrating, make sure contact points are clean and use appropriate handling tools or gloves to avoid fingerprints or contamination. Follow the procedures specified by your calibration or inspection protocol when recording measurements against the plate.

What to consider before purchase

• Required accuracy class for your application (verify if Class 2 meets your tolerances)
• Need for a certified reference — this product includes a calibration certificate
• Environmental control capabilities (temperature and cleanliness) where the plate will be used
• Compatibility with your measurement equipment and fixtures

Usage recommendations

Store the gauge block plate in its protective packaging when not in use, handle with clean gloves or tweezers, and perform periodic recalibration according to your facility’s schedule or the certificate’s validity period to maintain traceability and accuracy.
