Cygnus Instruments Cygnus manufacture ultrasonic thickness gauges which are employed in almost every industrial application worldwide. We also offer UT hatch cover tester.

We are the experts... Cygnus was founded in 1983

Founded in 1983, Cygnus pioneered the digital Multiple-Echo technique. This technique has long since been the industry standard for through coating measurement of material thickness. Driven by the need for a hand-held device, we successfully developed Multiple-Echo digital thickness gauges which measure metal thickness through protective coatings in a reliable and repeatable way. The range has recently been extended to include Echo-Echo and Single-Echo measurement modes to expand even further the usability of Cygnus gauges. Simplicity through technology…

Cygnus gauges are all robust and simple to use. They are engineered to withstand the harshest environments. New innovation…

Our roots are in marine inspection services. Now building on strong foundations, Cygnus has entered a new phase of innovation. We are investing heavily in market research and product development. We believe in an entirely application-driven, user-focused approach. For this reason we put a huge emphasis on listening to customer requirements and feedback. As a result of thousands of hours of research, development and continued investment, Cygnus has set and raised the standard for accurate thickness measurement devices, manufacturing gauges that are utilised in almost all industries including:

Ship hull surveys

Rope access surveys

Underwater inspections

Explosive environments. These are just a few of the diverse industries in which Cygnus thickness gauges are used. Remaining within the scope of using ultrasound for inspection, we have also developed the Hatch Sure, an ultrasonic hatch cover leak detector. Used predominantly for checking hatches on bulk carriers it also has many other applications e.g. water-tight door testing. Highest quality…

Cygnus is an ISO-9001 accredited company. On account of this and our intrinsically safe certifications (BASEEFA and CSA), we are constantly being audited guaranteeing you the best quality products. At Cygnus, high quality comes first and foremost.

🌍 Bringing Our Global Distributor Network Together!

At Cygnus Instruments, strong partnerships are at the heart of everything we do.

In September, we welcomed distributor partners from around the world to our Dorset headquarters for Learn & Connect — a special event focused on sharing knowledge, strengthening relationships and exploring opportunities for future growth.

From hands-on product demonstrations and technical discussions to exchanging ideas and best practices, it was a fantastic opportunity to bring our global community together and showcase the people, expertise and facilities behind the Cygnus brand.

A huge thank you to all our distributors who joined us and continue to represent Cygnus around the world. Here's to building stronger connections and achieving even more together! 🤝

⚓ Maintain structural integrity amid increasing inspection demands.

Corrosion in ballast, cargo and fuel tanks can progressively reduce steel thickness — potentially affecting vessel safety, class compliance and maintenance planning.

Cygnus ultrasonic thickness gauges provide fast, reliable wall thickness measurements to help inspectors detect metal loss early and make informed maintenance decisions.

Built for efficient marine tank inspections, Cygnus gauges can:

✅ Measure through protective coatings, reducing unnecessary surface preparation

✅ Provide instant visual A-Scan verification of every measurement

✅ Use Radial Points to assess surrounding areas and identify localised corrosion

✅ Help reduce inspection time and unnecessary downtime.

Reliable thickness data means greater confidence when assessing the condition of critical marine structures.

Prevent corrosion from becoming an environmental incident.

Corrosion doesn’t wait for an incident to happen. In hazardous industrial environments, early detection can make the difference between planned maintenance and an unexpected leak or failure.

The Cygnus 1 Ex enables ultrasonic thickness measurements in Zone 0, Zone 1 and Zone 2 hazardous areas, helping inspection teams monitor asset condition safely and accurately.

With reliable thickness data, you can make more informed maintenance decisions, extend asset life, reduce unnecessary waste and help prevent leaks before they become environmental incidents.

And with proven Multiple-Echo technology, measurements can be taken through paint and coatings — helping teams get the data they need without compromising protective coatings.

Protect your assets. Protect the environment.
