Is achieved through calibration using only hardness reference test blocks without any conversion tables which are "sewn” into the software of other hardness testers, thus increasing their measurement error.
Centre “MET” is a developer of high-precision portable hardness testers and hardness test blocks. Portable hardness testers guarantee reliable hardness control of metal products. MET hardness reference test blocks are measurement tools used to perform verification and calibration of hardness testers.
