CF-AN is a corrosion-preventing couplant for non-destructive testing and thickness measurement with ultrasonic waves.
CF-AN Coupling Fluid is necessary because sound energy at the ultrasonic frequencies typically used for ultrasonic testing is not effectively transmitted through air. Aside from damping effects, the air is a serious acoustic impedance mismatch with regard to both transducers/probes and test materials. Even an extremely thin air gap between the transducer/probe and the test material will prevent efficient sound energy transmission and make conventional testing impossible.
Optimal transmission requires an ultrasonic couplant without air bubbles that can reflect, scatter, and attenuate sound waves.
Temperature Range: -5 to 97 ºC
