Surface Probes

ECA Probes

Semi-flexible probes come with all the great features of rigid probes, but they can also easily bend to perform axial scans on convex and concave geometries with height variations along a single axis (such as pipes and floor plates).

The probes also come in a wide variety of frequency brackets, number of coils, and three casing sizes: small, medium, and large.


  • Flexible contact surface that adapts to height variations
  • High, uniform sensitivity
  • High resistance to wear and tear
