Surface Probes

ECA Probes

Our workhorse surface probes. Rugged and cost effective, they minimize lift-off for high, uniform sensitivity, making them the probes of choice for flat surfaces.

The probes are easy to handle and their design — from casing to retractable contact pins — makes them virtually infallible. Rigid probes come in a variety of frequency brackets, number of coils, and three casing sizes: small, medium, and large.


  • High, uniform sensitivity on flat surfaces
  • Easy to handle
  • High resistance to wear and tear
  • Cost effective
