Cygnus Underwater UT Tester
Ultrasonic Thickness Tester
Key features of the Cygnus Underwater ultrasonic thickness tester include:
- Multiple-Echo for accurate through-coat measurements, as specified by Classification Societies
- Deep Coat mode ignores coatings up to 20 mm thick (upon request)
- Heavy duty sealed unit with double O-ring protection
- Rugged, durable, shock-proof construction
- Easy and stable calibration – no zero adjustment
- Echo strength indicator to aid measurement
- Two rechargeable battery packs with charger
- APR (Auto-Probe Recognition)
- TSR (Topside Repeater) options:
Option A – Palm-held TSR or;
Option B – CygLink software for data logging and remote display.
Key benefits of the Cygnus pioneered Multiple-Echo technique include:
- Measures remaining metal thickness on corroded and coated structures
- All measurements are error checked using 3 return echoes to give repeatable, reliable results
- Accepted by all major classification societies
- Greatly reduces inspection time and costs
- Echo strength indicator to aid measurement.

To compliment Cygnus’ range of ultrasonic thickness testers we offer a range of portable UTM probes. The performance of any ultrasonic thickness tester relies heavily on the probe and its suitability to the material being tested. Therefore, selecting the right probe is vital.
All of Cygnus’ Single Crystal portable UTM probes are made from stainless steel and include replaceable membranes for long life, requiring no zeroing and have a high linear accuracy.

I received the Cygnus 1 in 1987 and used it continuously for 10 years on submerged pipelines, without any problems. After that period it was mainly used for ship board survey inspections of hull thickness testing which is still in use today with the same set of batteries. I cannot praise this piece of equipment enough as it has given unbeatable service in extremely hostile environments without failing at any time. I would recommend this unit to anyone looking for a reliable ultrasonic thickness testing unit.

Since my purchase of the Cygnus 1 Underwater gauge in 2005, I have had no problem with the gauge, and it’s still going strong after 14 years of use by divers, completing many underwater inspections across countries in Africa and Europe. There were times where it wasn’t easy to get readings on odd surfaces or through small marine growth, but we succeeded eventually.

There are many in the industry who have been using Cygnus meters for more than 20 years. I myself have used their underwater thickness gauge along with regular and Intrinsically Safe UT meters from the early stages of my career – and that goes back to more than 25 years for sure. TechCorr, a global leader of inspection services, uses Cygnus Gauges for pipelines, tanks and vessel inspections. Our operators particularly love Cygnus – as readings come quick and accurate.
