In the marine sector, reliable inspection tools are critical for ensuring safety, structural integrity, and regulatory compliance - particularly in hazardous environments. Accurate thickness measurement helps minimise the risk and controlling maintenance costs. Cygnus Instruments, a leader in digital ultrasonic testing (UT), provides robust, data-driven thickness measurement gauges like the Cygnus Underwater and Cygnus 1 Ex - engineered to perform in harsh marine environments across applications including ship surveys, hull and tank maintenance, offshore structures, and port infrastructure.

Shorter, Safer, Smarter Dives

Take advantage of 20% off the Cygnus Underwater with the Trade-In Offer (promo code: UWTI26). Trade in any subsea UT gauge - diver-held or ROV-mounted, any brand, age, or condition.

For commercial diving teams, the Cygnus Underwater delivers fast, reliable measurements - even through coatings and heavy corrosion - while reducing diver workload. Every second underwater increases cost and risk, so efficiency is critical. Its Multiple-Echo capability, intuitive controls, bright LED display, and rapid verification features reduce time spent stabilising probes, repeating readings, or removing coatings.

The result is quicker, more confident measurements, shorter dive times, and reduced exposure - even in low visibility or high-risk conditions such as dams, sluices, and turbulent waters.

Key features include:

Integrated depth sensor;
Live A-scan visual verification;
Multiple-Echo through-coat measurement;
Measurement Stability Indicator (MSI);
Automatic time-stamped data logging.

Lightweight and easy to operate, the Cygnus Underwater supports safer, faster inspections with dependable data.

Cygnus 1 Ex: Safe Inspection in Hazardous Environments

In offshore platforms, tankers, and fuel terminals, inspections must be performed without halting operations or increasing risk. The Cygnus 1 Ex ultrasonic gauge enables safe, in-service thickness measurement in explosive atmospheres. It is certified intrinsically safe (ATEX, IECEx, UKEX) for Zones 0–2, allowing inspections without shutdowns or hot work permits.

Paired with the Cygnus High Temperature Ex Probe, it measures at temperatures up to 300°C, making it ideal for live steam systems, vessels, and pipework without cooling delays.

Designed for demanding marine environments, it improves efficiency by enabling:

Inspection of live assets with no shutdowns or disruption;
Elimination of hot work permits;
Through-coating measurement up to 20mm;
Single-sided access in confined spaces;
High-temperature inspection at operating conditions.

Multiple-Echo technology ensures fast, repeatable accuracy through coatings, reducing preparation time and rework. Built-in safety features allow inspectors to focus entirely on performance.

Complete Marine Integrity Solution

Together, the Cygnus Underwater and Cygnus 1 Ex provide a comprehensive solution for maintaining marine asset integrity - enhancing safety, reducing costs, ensuring compliance, and extending asset life above and below the waterline.
