Alternating Current Field Measurement (ACFM)
Non-invasive detection of surface-breaking flaws in conductive materials with crack depth measurement.

Alternating Current Field Measurement (ACFM) is a non-invasive technique designed for detecting surface-breaking flaws in conductive materials. By utilizing alternating currents, it provides accurate measurements of crack depth and location, ensuring the integrity of your assets while minimizing operational downtime.
ACFM requires minimal surface preparation and works through coatings, making it ideal for in-service weld inspection on offshore platforms, storage tanks, and structural members where blasting is impractical.
