CYG002-CYGNUS 1 UNDERWATER ULTRASONIC THICKNESS GAUGE
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 metres and it provides an accurate metal thickness measurement through coatings up to 20mm thick. The bright LED display ensures easy viewing even in poor visibility conditions.
The Underwater Thickness Gauge is supplied ready to use as a complete kit with 2 rechargeable batteries in a protective carry case.
