A diver-held subsea ultrasonic thickness testing device designed for in water survey and underwater inspection in-lieu of drydocking, providing accurate and reliable through coating measurement.
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.

Options
TSR Remote Display Unit
TSR is a remote display unit connected to the underwater tester with an umbilical cable and displays the thickness measurements at the surface in real-time during the survey.
TSR options: (A) Palm-held TSR or; (B) CygLink software (Windows based) for data logging and remote display.
CygLink Software
CygLink is a Windows® based application used to display, log and transfer thickness measurements at the surface. The software can generate PDF reports and export to CSV files, allowing for ‘after the event’ analysis of logged measurements. Designed for Windows 7 and above.
