Alternating Current Field Measurement (ACFM®) is an advanced Non-Destructive Testing (NDT) technique designed to detect and size surface-breaking cracks in metals through coatings with an excellent surface tolerance compared to PEC.

Features ACFM MPI ECT*
Reduced operator dependence
  • Better detection reliability and repeatability
  • Greater confidence of data integrity
Detection through coatings
  • Avoids cost and coating removal
Detection under ambient light. No pollutants.
Detection in duplex and other non-magnetic materials
Remote deployment
  • Enables deepwater deployment (down to 2000 m)
  • Access to locations where diver safety is a concern
  • Reduced cost of DSVs, dive systems, and spreads
Provides accurate and auditable inspection records
  • Enables effective integrity and risk management
  • Supports regulator verification and audits
Determines crack length and depth without calibration
High probability of detection (PoD) and low false call rate
  • Avoids unnecessary repairs, rework, and costs
Robust technology – insensitive to temperature
