Cygnus Instruments, a global leader in ultrasonic testing (UT) technology, has unveiled its latest range of ultrasonic thickness gauges tailored to the maritime and offshore industries. The launch reinforces Cygnus’ longstanding commitment to precision, rugged design, and operational simplicity in corrosion inspection—particularly on coated surfaces.
With over four decades of collaboration with ship surveyors and commercial divers, Cygnus has developed a portfolio of instruments engineered to withstand the harsh realities of marine environments. The new Cygnus Surface Range is designed to address one of the industry’s most pressing challenges: measuring corrosion without compromising protective coatings.
Corrosion remains a significant threat to marine vessels and offshore structures, with saltwater and humidity accelerating structural degradation. However, removing protective coatings for inspection introduces operational delays and increases exposure to further corrosion risk. Cygnus' pioneering Multiple Echo technology bypasses this problem by allowing accurate readings of substrate thickness while ignoring any coatings—an innovation that reduces cost, time, and inspection-related risks.
The Cygnus 4+ ultrasonic thickness meter integrates advanced features like live A-scan displays for visual verification, a large colour screen, and onboard data logging. These enhancements streamline reporting and boost confidence in field measurements. The device also incorporates a Measurement Stability Indicator (MSI), providing instant feedback on reading reliability—critical for surveyors operating in challenging conditions.
For inspectors working at heights or in confined areas, the Cygnus 2+ offers a compact design with a rotatable end-mounted display, optimised for rope access and climbing inspections. Both models are multi-mode devices capable of inspecting coated, uncoated, and heavily corroded surfaces, backed by a three-year warranty.
Constructed to IP67 standards, the UT gauges are shatterproof and water-resistant, and compatible with Cygnus’ wide selection of single-crystal, twin-crystal, and right-angle probes. This versatility ensures flexible access to awkward geometries and narrow spaces.
With a legacy of innovation since 1983, Cygnus continues to elevate safety and efficiency across the global marine and energy sectors—empowering surveyors with accurate data without sacrificing protective infrastructure.
