Remote Field Testing System

Adept-Pro Software

  • Integrates examination planning, data acquisition, analysis, and report generation
  • Voltage plane display and analysis for maximum flaw information
  • Specialized Remote Field analysis channels including support plate suppression and uniform wall loss signal filter

Ferroscope TT instrument

  • Inspect stainless steel superheater tubes for internal flakes from exfoliation
  • Super-critical boiler application
  • Magnetic flakes accumulate in the bottom of the pendants and eventually choke off the steam flow leading to tube failure
  • Special TT probes for all sizes of superheater tubes


  • Our experienced trainers are available for a custom training course at your facility or ours
  • ASNT-TC-1A eligible courses in RFT and ECT
  • Certificate courses


Equip your Ferroscope 308 with a wide selection of accessories.

  • I-Pit Probes
  • E-Pit Probes
  • VertiScan System including TubeCAT Wall Crawler  
  • Bracelet Probes

 Additional Information

  • Awards: Russell NDE has won two ASTech Awards for Industrial Design plus a Frost and Sullivan award for Best Practices.
  • Both awards relate to RFT technology employed in the Ferroscope and other Russell products.
