About Cygnus

Cygnus Instruments was incorporated in 1983. Our original line was focused on the NDT of ship hulls but has grown to include a full range of UT thickness meters as well as Ultrasonic Hatch Leak Detectors, Ultrasonic Tightness Testing and Flooded Member Detection equipment. Everything is made by us in the UK to the highest standards and we are proud of our extensive global customer support network. Our specialism is highly ruggedized and simple to use UT equipment for corrosion inspection, subsea IRM and asset integrity management (AIM).
