Cygnus Instruments

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 i

n 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.

A gauge that outlasted expectations.

In the early 1990s, a diver purchased a Cygnus 1 Underwater Ultrasonic Thickness Gauge. For more than two decades, it faced the demands of underwater structural inspections - corrosion, coatings and the rough handling that comes with diving work.

After years in storage, the gauge was brought back out… and it was still ready to work.

That’s the Cygnus legacy of reliability. And now, that legacy continues with the new Cygnus Underwater Diver-Held Gauge built with the same focus on dependable performance, alongside new and updated features.
