Pulsed Eddy Current Probe for Galvanized Steel Cladding

The best tool for a deep dive into corrosion detection

Eddyfi Technologies offers the PEC-GS probe which was specifically designed to detect Corrosion Under Insulation (CUI) in the presence of galvanized steel weather jackets.


  • Scan through 1 mm (0.04 in) galvanized steel with excellent detection and sizing capabilities
  • Maximum signal penetration
  • Better Signal-to-Noise Ratio (SNR)
  • Scan through metal up to 38 mm (1.5 in) thick
  • Scan through insulation 13–152 mm (0.5–6 in) thick


No matter the weather (jacket), prevent the next storm

Lyft® now includes the PEC-GS probe dedicated to inspecting insulated structures protected by galvanized steel weather jackets. Being ferromagnetic, galvanized steel cladding is a challenge for PEC inspections. Designed to overcome the adverse effects of this material, the patent-pending probe ensures:

  • Improved signal penetration
  • Excellent detection capabilities and sizing accuracy
  • Enhanced SNR

Eddyfi Technologies' galvanized steel cladding pulsed eddy current probe supports metal thicknesses up to 38 mm (1.5 in), insulation 13–152 mm (0.5–6.0 in), and galvanized steel weather jackets up to 1 mm (0.04 in) thick. The probe is capable of scanning pipes with diameters as small as 25 mm (1 in) and has an extension cable (15 m/50 ft) for rope access (sold separately).

To summarize, the pulsed eddy current probe for galvanized steel cladding by Eddyfi Technologies is a highly advanced non-destructive testing technology that enables precise and reliable inspection of metal structures. With its ability to detect corrosion and erosion beneath paint, coatings, and insulation, our PEC probe provides asset owners and inspectors with critical information for maintaining the integrity of their assets.

If you are looking for an advanced NDT inspection solution for detecting hidden corrosion in galvanized steel, you need to incorporate the PEC probe into your inspection and maintenance programs.
