Ultrasonic Flaw Detection >> Couplants >> Special Application Couplants
Sonotech : High Z, LV/HV
 
HIGH Z is well suited for testing on curved, rough and/or corroded surfaces that require a high acoustic impedance. HIGH Z provides the highest acoustic impedance of all Sonotech couplants, thus reducing surface noise and improving coupling performance for flaw inspection or thickness gauging metals, especially those with rough surfaces.
