A coupling medium must be used for the coupling of the ultrasonic probes to the test object. Different oils and predominantly water are used for this. For use in practical training it is recommended that an ultrasonic gel from medical diagnostics should be used, because these gels have a high viscosity but do not contain any oily constituents (there is no danger of contamination). The ultrasonic gel is non-toxic, water-soluble and skin-compatible.
