Hardness calibration services
We provide ISO 17025 accredited and traceable hardness calibration services, whether at our laboratory or on your site.

Why choose our hardness calibration services
Your equipment can’t crack under pressure, otherwise so do your operations. Hardness testers repeatedly measure the relative resistance of materials to denting, bending or scratching and can become misaligned. Trescal provides full hardness calibration services that are ISO/IEC 17025 accredited, whether at our laboratory or on your site. Accreditation for our hardness calibration service guarantees traceable results to the International Systems of units (SI).
