TM-U3 Ultrasonic Hardness Tester with HV/HB/HRC Scale UCI Method

The TM-U3 ultrasonic hardness tester can nondestructively measure metals and alloys with a minimum thickness of 3 mm. It is suitable for measuring strip/plate workpieces, mold hardened layers, blade hardened layers, tooth surface hardened layers, flange edges, wheels, turbine rotors, thin plates, shafts and pipes, containers, knife edges, welding parts, and more.
