SonoDur3: The original stands out with its technology and innovation

NewSonic once again proves its high competence in development of test devices and systems in UCI (Ultrasonic Contact Impedance) hardness testing technology.

The SonoDur3 is exemplary in terms of a good overview and uncomplicated handling, just as its predecessor SonoDur2 was. Nevertheless, it shows ground-breaking improvements as compared to the predecessor model.
