Cygnus 4 General Purpose
Ultrasonic Thickness Tester
Key features of the Cygnus 4 General Purpose ultrasonic thickness tester include:
- Multiple-Echo for accurate through-coat measurements, as specified by Classification Societies
- Deep Coat function ignores coatings up to 20 mm thick
- Min/Max measurement limit functions
- Visual and vibrate alert
- Simple, one-point calibration – no zeroing required
- Intuitive easy to use menu
- Large and bright front colour LCD display
- Extremely rugged enclosure – shock and impact proof to US MIL STD 810G
- Environmental sealing (water and dust proof) to IP67 – US MIL STD 810G
- Can be upgraded to 4+ or 6+ at an additional cost.
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.

Thank you Cygnus. You have been awesome in your support on ALL our inspections for over 20 years. 60 machines including our first machine bought 20 years ago (Cygnus 4, Sr. No 300), are all still in operation. That is a testament to Cygnus’ quality engineering and electronics.
