Trade in any subsea UT thickness meter, diver held or ROV mounted, any brand, any age, any condition, to upgrade to Cygnus Underwater, featuring automatic data logging, a high-visibility LED display for low-light conditions, live A-scan display, and an integrated depth sensor.
Designed for subsea corrosion surveys, the Cygnus Underwater diver-held meter delivers fast, accurate thickness measurements through coatings and heavy corrosion, reducing diver workload and bottom time.
A high-visibility LED display ensures clear readings in low-light, turbid water, while simple three-key operation keeps divers focused. Multiple-Echo, live A-scan, and a Measurement Stability Indicator (MSI) provide reliable results, with automatic logging reducing errors, missed points, and re-dives.
Faster measurements mean:
- No coating removal
- Less probe stabilisation
- Fewer repeat readings
- Reduced struggle with currents and surges
- Improved diver safety.
Rugged, shockproof, and double O-ring sealed, Cygnus Underwater is engineered for confined spaces, turbulent harbours, and demanding offshore conditions.
Cygnus 6+ PRO: High-Performance Corrosion Monitoring
Corrosion is a persistent issue in marine environments, as hulls, decks, tanks, and steel structures are constantly exposed to saltwater, humidity, and temperature changes that accelerate material degradation.
Cygnus 6+ PRO is an advanced ultrasonic thickness meter for detailed corrosion assessment. Lightweight, compact, and IP67 rated, it performs reliably in confined and exposed environments, with one-sided measurement ideal for limited access areas.
Using Cygnus’ proprietary Multiple-Echo technique, as specified by IACS and individual maritime classification societies, the Cygnus 6+ PRO can measure material thickness through coatings up to 20 mm, eliminating the need for coating removal and enabling faster marine inspections during tight operational windows.
Key features:
- High-contrast colour LCD for clear readability
- End-mounted display with hands-free accessories for rope access
- Three measurement modes for clean, coated and heavily corroded surfaces
- Measurement Stability Indicator (MSI) for real-time validation
- Live A-scan for visual verification
- Manual gain and range controls for challenging materials
- Comprehensive data logging with auto log
- Radial Points enable additional multi-point assessment around heavily corroded spots.
- Bluetooth and cable connectivity for easy reporting
A Unified Approach to Marine Asset Integrity
Cygnus Underwater and Cygnus 6+ PRO form a comprehensive ultrasonic marine inspection toolkit supporting:
- Increased safety and efficiency
- Lower inspection and maintenance costs
- Regulatory compliance
- Extended asset life.
Cygnus Instruments remains a trusted partner for shipowners, ports, surveyors, and marine engineers seeking accurate and durable inspection technology to perform above and below the waterline.
