Measurements of hardness and microhardness

Hardness measurements are a basic form of checking the quality of material in order to verify the correctness of thermal procedures as well as the compliance with international standards, technical documentation, and material certificates.

We make:

Brinell’s (ball diameter 1 mm; 2,5 mm; 5 mm), Vickers’ and Rockwell’s (0,5 kg – 250 kg) hardness measurements

Shore’s hardness measurement (scale A and D)

microhardness and hardness measurements at lowered load (5 g – 2000 g)

hardness and thickness measurements for surfaces hardened through diffusion and/or tempered

determination of the depth of decarburization using hardness measurement at lowered load

hardness measurements of plastics
