The Cygnus Mini ROV Thickness Gauge is a compact ultrasonic NDT instrument designed for installation on small inspection ROVs. Using Cygnus Multiple Echo technology, it accurately measures metal thickness without removing coatings, even on rough or corroded surfaces. The unit is pressure tested to 500 m, making it ideal for subsea and offshore inspections.
