ABSTRACT:
A composite analyzer probe, for use with a composite analyzer tester instrument for nondestructively testing and analyzing the physical properties and gaging the thickness of a test material. A cylindrical probe housing has a generally flat end surface designed to be placed flat against the surface of the test material. An annular magnetic induction coil is positioned against the end surface, a piezoelectric element having a hollow cylindrical casing is positioned within the annular magnetic induction coil, and an eddy current coil is positioned within the piezoelectric cylindrical casing. The single improved probe allows four different measurements to be taken at one location on the test material without any required movement or replacement of the probe.
