L’ “HARDMATIC” HH–411 è uno strumento portatile leggero, per la prova della durezza supezzi in metallo.Compensazione automatica d’angolazione dell' impugnaturaFunziona secondo il principo del rimbalzo del penetratore (dardo) su pezzo in misura (in accordo alle ASTM A 956).Rileva la durezza L (Leeb) e la converte nella scala di durezza desiderata.Visualizza automaticamente il risultato del giudizio GO/±NO GO quando impostatoIn grado di memorizzare fino a 1800 valori di misura.Con il software Expak 11AAC238 e possibile effetttuare la raccolta dei dati misurati
