Founded in 1983, Cygnus Instruments Ltd is the leading manufacturer of multiple-echo ultrasonic thickness gauges. The Cygnus multiple-echo technique has long been a gold standard in several industries and endorsed by the world’s leading classification societies for measuring metal thickness through protective coatings. The multiple-echo technique delivers accurate and error-checked metal thickness measurement readings, simply and effectively.
The Cygnus range of thickness gauges includes: the wrist-mountable Cygnus DIVE with live A-scan and B-scan displays for subsea thickness measurement verification to 300 msw; the RINA-type approved Underwater model designed for divers taking thickness measurements, also to 300 msw; the Intrinsically Safe model, certificated to ATEX and CSA; the ROV-mountable series with probe handling solutions; and the Heavy Duty model. In 2015, Cygnus launched a full range of new hand-held thickness gauges that bring to bear over 30 years of intimate industry knowledge and combine it with the company's engineering expertise. The range includes many industry-standard features, such as A-scan, B-scan and data logging. Intuitive and extremely simple to use, Cygnus’s new units will also carry certification that marks them out as being the most rugged on the market.
In addition to thickness gauges, Cygnus has Cygnus Hatch Sure, which is used for testing the weather tightness of hatch covers.
