Since 1983, Cygnus Instruments has been a leading manufacturer of digital ultrasonic thickness gauges (UTG), focused on reliable corrosion inspection and asset integrity management.

Cygnus’s most advanced and distinctive product is the Cygnus 1 Ex—the world’s only Zone 0 ultrasonic thickness gauge. This Ex gauge is not only safe but also certified as intrinsically safe under ATEX, IECEx, and UKEX standards for all hazardous Zones 0, 1, and 2.
Zone 0 Oil and Gas Terminal Inspections
The Cygnus 1 Ex ultrasonic thickness gauge is a valuable tool for safe structural inspection of oil and gas terminals. Users have described it as “versatile, multifunctional, robust, and intuitive.”
This intrinsically safe gauge provides reliable control and flexibility, removing the need for plant shutdowns or Hot Work permits. With three measuring modes and a range of probes, the gauge can measure various materials and metals with heavy corrosion or protective coatings (up to 20?mm thick), helping save time and cost by avoiding coating removal.
Thanks to adjustable settings, Manual Measurement Mode makes it easier to take accurate readings in difficult areas, such as those affected by severe corrosion.
Like a flaw detector, users can manually adjust two gates, place them anywhere on the A-scan, change gate height, start point, and width, and measure from a gate or between gates. Time-Controlled Gain (TCG) allows different gain levels to improve weaker echoes.
For data storage and analysis, the gauge offers flexible options. Logging supports linear, template, and 2-D or 3-D grid formats, with 16 grid patterns and the ability to add annotations.
Radial Points allow further inspection around areas of interest or heavy corrosion, with up to 12 additional measurements recorded around the main one.
Efficient and Precise Storage Tank Leak Inspections
The Cygnus Hatch Sure Ultrasonic Tightness Tester is a fast, reliable, and environmentally friendly system for detecting leaks and checking the seal integrity of any opening that needs to be sealed.
Speed and convenience are central to its design. Inspections can be carried out without clearing the space, making it ideal for large storage areas where seal integrity is important, but moving contents for inspection would be inefficient.
Hatch Sure’s battery-powered transmitter is strong and durable. It contains 19 ultrasound emitters (40?kHz) arranged to produce an omnidirectional sound field evenly distributed throughout the space.
The receiver shows the sound energy level that passes through, allowing users to quickly and accurately locate leaks. Six selectable preset power levels help adjust for different space sizes, including confined areas.
The Cygnus Hatch Sure system is simple to use and designed for one-person operation, helping save both time and cost.
