Let wel:
1. Brinell-hardheid: Dit word hoofsaaklik gebruik om die hardheid van gietstukke, smeedstukke, nie-ysterhoudende metaalonderdele, warmgewalste billets en gegloeide onderdele te meet. Die meetbereik is ≥HB450.
2. Rockwell-hardheid: HRA word hoofsaaklik gebruik vir hoë-hardheidsmonsters om die oppervlakhardheid van materiale en oppervlaktes met 'n hardheid hoër as HRC67 te meet, soos gesementeerde karbied, genitrierde staal, ens. Die meetbereik is HRA> 70. HRC word hoofsaaklik gebruik om die hardheid van staalonderdele (soos koolstofstaal, gereedskapstaal, legeringsstaal, ens.) na afblus of tempering te meet. Die meetbereik is HRC20~67.
3. Vickers-hardheid: word gebruik om die hardheid van dun dele en staalplaatdele te meet, en kan ook gebruik word om die hardheid van oppervlakverharde dele soos karburering, sianied en nitride te meet.
