Cygnus Instruments Underwater Ultrasonic Thickness Gauge

The Cygnus Instruments Underwater Ultrasonic Thickness Gauge is the original diver held subsea multiple echo ultrasonic thickness gauge. Cygnus Underwater instruments possess a pressure rating of up to 300 meters (1,000 ft) and provides an accurate metal thickness measurement through coatings up to 20 mm (0.787 in) thick using Deep Coat mode (upon request). The Cygnus Underwater thickness gauge is designed with a bright LED display that ensures easy viewing even in poor visibility conditions.
