Gekko Phased-array Flaw Detector Fixed (2025)

Subsea riser corrosion mapping. Using a 7.5MHz dual-linear array, the Gekko can discriminate between pitting corrosion and generalized wall loss in carbon steel under coated surfaces.

For decades, conventional ultrasonic flaw detection has been a cornerstone of non-destructive testing (NDT). However, the inherent limitations of single-crystal probes—namely slow scanning speeds and difficulty imaging complex geometries—have often left inspectors with ambiguous signals. Enter the Gekko Phased-Array Flaw Detector. Designed not just as an instrument, but as a mobile inspection ecosystem, the Gekko is changing how engineers visualize integrity in critical assets. Unlike conventional single-probe ultrasonics, phased-array systems use a multi-element probe (typically 16 to 256 individual piezoelectric elements). The Gekko’s software fires these elements in precise, timed sequences (phasing) to steer, focus, and sweep an ultrasonic beam electronically. gekko phased-array flaw detector

The Gekko is not the cheapest phased-array unit on the market (starting at $28,500 USD), but for asset owners facing expensive unplanned downtime, the cost of missing a single defect is far higher. With its blend of raw processing power and user-centric design, the Gekko Phased-Array Flaw Detector is the new benchmark for portable ultrasonic imaging. Subsea riser corrosion mapping
