ECT Magnetic Saturation Bobbin Probes


  • Stainless steel body
  • Replaceable, hardened-steel wear guide
  • Highly kink-resistant cable
  • 4-pin amphenol connector


Our magnetic saturation bobbin probes are designed to inspect ferritic and Duplex stainless steels, as well as nickel-based alloys commonly found in condensers and feedwater heaters, among others.

Powerful, rare-earth magnets in the probe completely saturate the tube wall, making it possible to use inspection frequencies usually reserved for the inspection of non-ferromagnetic materials.

Our probes are designed to detect and size inner-tube diameter pitting, outer-tube diameter wear, and other common types of defects. The kink-resistant nylon cabling is perfect for manual and automated push-and-pull operations.
