RELIABLE ULTRASONIC MEASUREMENT CYGNUS UNDERWATER ULTRASONIC THICKNESS GAUGE Specifically designed for divers undertaking ultrasonic thickness measurement (UTM) of underwater structures, the Cygnus Underwater has been built to withstand harsh subsea environments while providing quick and accurate metal thickness measurements through coatings or heavy corrosion. This diver-held gauge is simple to operate using 3 function keys, an intuitive menu and a large LCD display – highly visible, even in low-visibility waters. IDEAL FOR USE IN HULL UTM INSPECTION CIVIL ENGINEERING MARINE STRUCTURES OFFSHORE PLATFORMS ...underwater structures, e.g. bridges, tanks, canal locks, subsea pipelines and equipment, UWILD or IWS class surveys.

CYGNUS UNDERWATER CYGNUS UNDERWATER KEY FEATURES 3 measuring modes for levels of corrosion, various materials and through-coat measurements Depth sensor - live depth display providing the diver with an accurate depth indicator Live A-Scans aid visual measurement verification Extremely Simple-to-Use with 3 function keys and up to 4 screens Comprehensive data-logging: linear and grid Deep Coat function ignores thick coatings RTC (Real Time Clock) for tagging date/time on measurement points Auto-set Gain to optimise the probe’s gain settings for optimal performance Multiple Echo Mode to verify...

SELECTABLE OPTIONS Comprehensive Data Logging Record types: Linear and Grid 2D Log measurements by pressing the middle key or using Auto-Log feature Allows a maximum of 5,000 measurement points per record 16 grid patterns available Saves measurements with A-scans and depth as records on internal memory • • • Three Selectable Measuring Modes Multiple-Echo mode uses three error checked back wall echoes to provide the most reliable and accurate remaining thickness measurements, with no need to remove coatings (up to 20mm/0.8 in thick). Single-Echo mode is ideal for measuring uncoated metals...
