INSIZE reference gauge plate 103 class 2 (model 4100-2103) — calibration/measurement standard

INSIZE reference gauge plate 103 class 2 (model 4100-2103) is a precision calibration standard plate designed for use as a stable datum in measurement and verification tasks. Manufactured by INSIZE for measuring tools applications, this class 2 gauge plate provides a known, repeatable reference surface for calibrating instruments, comparing gauges and performing routine dimensional checks in workshops and quality-control laboratories.

Advantages

The gauge plate offers a flat, stable reference surface with class 2 accuracy suitable for everyday calibration and inspection workflows. Its construction ensures dimensional stability under normal workshop conditions and facilitates repeatable comparative measurements. The product is compact and straightforward to handle, enabling quick setup and use during verification procedures.

Suitable for

• Calibration and verification of dial indicators, comparators and height gauges
• Comparative checks and routine dimensional inspections in production and QA labs
• Establishing a reference surface for bench measurements and tool setup

When it may not be suitable

This class 2 gauge plate is intended for standard calibration and verification tasks rather than high-precision laboratory reference standards. It may not meet the tighter tolerances required for accredited calibration labs or metrology applications that demand class 0 or class 1 accuracy. For use in environments with extreme temperature variation, additional environmental control or higher-grade standards should be considered.

Key specifications

• Accuracy class: Class 2
• Function: Reference/calibration gauge plate for dimensional measurement
• Primary use environment: Workshops, inspection benches and quality-control labs
• Typical applications: Calibration, comparative measurement and verifications

How to use

Place the gauge plate on a clean, stable surface or surface plate and ensure it is free from debris and contaminants before use. Bring the instrument or gauge into contact with the reference surface according to the manufacturer’s instructions and perform comparative readings or adjustments. Allow the plate to acclimatize to the workshop ambient temperature for accurate results and handle it with care to avoid scratches or dents that could affect measurement reliability.

What to consider before purchase

• Required accuracy class for your calibration tasks — class 2 is suitable for routine verification but not for highest-precision metrology
• Working environment and temperature control — stable ambient conditions improve measurement repeatability
• Compatibility with the instruments and gauges you intend to calibrate

Usage recommendations

Use the INSIZE reference gauge plate as a stable, repeatable datum for routine calibration and comparative checks. Keep the plate clean and store it in a protective case when not in use. For traceable or laboratory-grade calibrations, verify that the accuracy class meets your certification requirements or consider higher-class standards.
