  • NDT of non-conductors, that means Non-Destructive Testing (NDT) of dielectric materials and parts. For this we use the microwave testing (µT).  

  • Expert advice on the NDT of non-conductors, inluding feasibility studies as well as placement of reliable and qualified manufacturers and suppliers and service providers.

  • Regarding the NDT of non-conductors please contact Johann Hinken , Tel.: +49 171 2053208, email: johann.hinken@fitm.de
