    Product Description

    Ernst is officially authorised to provide DYNATEST SCX with an ACCREDIA (UKAS equivalent) calibration certificate, in accordance with DIN 50157-2.

    Portable hardness tester applying a heavy force (DIN 50157), comparable to standard Rockwell forces. Fundamental is the fact that testing is not influenced by any deflection, elasticity or mass of the work piece. All this has been obtained by developing a new dynamic system, which radically differs from the known ones where the test force, being achieved by impact, is not precise but depends on the reaction it meets; for this reason, these other systems can be used only for testing considerable masses free of deflection. On the contrary, with the DYNATEST SCX, the force acts progressively on the indenter in a very short time but without impact.
