Eddy current testing (ET)

The eddy current test can be used to examine electrically conductive parts for microscopic flaws near the surface such as pores, inclusions and cracks. This method can also be used to test material properties: layer thicknesses can be tested, and the structure can be examined based on small changes in the conductivity of the parts. Due to workpiece-dependent test strategies, various probes, scanners and coils are used.


  • Layer thickness measurements of non-magnetic materials on FE metals and non-electrically conductive materials on NE metal (including cooper, zinc, aluminium)
  • Mobile and stationary tests (under construction site conditions)
  • Single part and series testing
