The Cygnus 6+ Pro Ultrasonic Thickness Gauge is the top-tier model in the Cygnus handheld range, combining advanced ultrasonic functionality with unmatched durability and precision. Designed for professional inspectors, it features Multiple-Echo, Echo-Echo, and Single-Echo measurement modes for thru-coating and corroded metal applications. The 6+ Pro offers dual LCDs (front and end-mounted), A-Scan and B-Scan displays, temperature compensation, and Bluetooth data transfer. Its comprehensive data logging system supports linear, 2D grid, and radial logging for complex inspection surveys. Built to MIL-STD-810G and sealed to IP67, the Cygnus 6+ Pro is engineered for demanding oil and gas, marine, energy, and process environments — even at high temperatures up to 572°F (300°C) when used with the optional high-temperature probe.
