Tubing Probes


RFT can detect and size all the typical defects in ferrous tubes — steam erosion, corrosion, baffle cuts, and pitting. Eddyfi offers several RFT probes to measure wall loss, to size pitting, and to detect flaws hidden by support plates in feedwater heaters, heat exchangers, and piping.

Eddyfi’s RFT double-driver probes are designed for differential signal analysis and detecting corrosion, erosion, wear, and pitting close to tubesheets. The probe is sleeved in stainless steel for increased durability up to a probe diameter of 18 mm (0.71 in), inclusively. From this diameter up, the probe’s body is sleeveless and made of advanced, light polymer.


  • Excellent for differential signal analysis
  • Above-average durability
  • Low friction noise
  • High quality-to-price ratio
