The T-5630 ultrasonic hardness tester can measure the hardness of metals and alloys non-destructively, as long as they have a minimum thickness of 3 mm. It is suitable for measuring the hardness of various components including strip/plate work-pieces, hardened layers, blade hardened layers, tooth surface hardened layers, flange edges, wheels, turbine rotors, thin plates, shafts and pipes, containers, knife edges, and welding parts.
