CYGNUS UNDERWATER
The Cygnus Underwater is the original diver held subsea multiple echo ultrasonic thickness gauge. It was designed for use by divers undertaking subsea maintenance and surveys 3 decades ago… and today it is still the industry standard.
The unit is depth rated to 300 meters (1,000 ft) and it provides an accurate metal thickness measurement through coatings up to 20 mm (0.787 in) thick using Deep Coat mode (upon request). The bright LED display ensures easy viewing even in poor visibility conditions.
The Cygnus Underwater thickness gauge is supplied ready to use as a complete kit with 2 rechargeable batteries in a protective carry case.
Cygnus Instruments builds all of its equipment in the UK using only genuine and original parts and components – including Lemo® Connectors and Peli® Cases.

TOPSIDE REPEATER OPTIONS
The Topside Repeater is used when the readings need to be verified on the surface. Umbilical cable length is specified by the customer up to a maximum of 1,000 m. There are three options available:
Option A: Palm held surface display repeater with large liquid crystal display in an IP65 sealed case.
Option B: Data logging and remote display Windows based *Cyglink Software. (*For more details, visit the CygLink Software page in PRODUCTS > THICKNESS GAUGING ACCESSORIES section).
Also available, the Cygnus DIVE wrist-mountable underwater thickness gauge as an alternative for diver use. For more information, visit Cygnus DIVE page and watch the Cygnus Instruments underwater ultrasonic thickness gauge video.
