Cygnus Instruments

Cygnus Instruments is the world’s leading pioneer in the development of ultrasonic thickness (UT) gauges for the offshore industry. Founded in 1983, the company revolutionized subsea inspection by introducing the “Multiple Echo” digital thickness gauge. Based in Dorchester, UK, Cygnus Instruments has spent over 40 years establishing itself as the gold standard for Non-Destructive Testing (NDT) in harsh marine environments.

As a specialist in ultrasonic technology, Cygnus is best known for its ability to obtain accurate metal thickness measurements without removing protective coatings. Their “Multiple Echo” technology reads through paint, rust, and marine growth, displaying only the metal thickness. This significantly reduces inspection time and preparation costs, as divers do not need to grind back coatings to get a reliable reading.

In addition to their handheld units, Cygnus manufactures the industry-favorite “Cygnus DIVE,” a robust, wrist-mountable gauge with a large, bright AMOLED display. Designed to free up the diver’s hands, it is depth-rated to 300 meters and features an “A-Scan” display for verifying measurements in real-time. For deeper operations, Cygnus offers a range of ROV-mountable gauges that can be manipulated by work-class ROVs or mounted on small observation vehicles, ensuring accurate data collection at any depth.
