- Measurement Range in Steel: Approx. 1 – 250 mm (0.04 – 10.0 in) depending on probe choice and configuration.
- Measurement Resolution: Selectable resolution (e.g., 0.1 mm or 0.05 mm) depending on probe and mode.
- Measurement Accuracy: Typical accuracy around ±0.1 mm or 0.1 % of reading when properly calibrated.
Description
Ultrasonic Thickness Gauge Cygnus Underwater – is a high-performance subsea measurement instrument designed for precise and reliable ultrasonic wall thickness measurement of underwater metal structures. Engineered for use in harsh marine environments, this diver-held gauge provides accurate remaining wall thickness readings through protective coatings and corrosion, making it ideal for ship hull surveys, offshore platforms, subsea pipelines, piers, and other submerged assets. Its robust construction and bright display ensure dependable performance even in challenging underwater conditions.
Key Features
- Diver-Held Design — Ergonomic and rugged for ease of use by commercial divers during underwater inspections.
- Large Visible Display — Bright LCD screen designed for clear viewing even in low-visibility waters.
- Three Ultrasonic Measuring Modes — Includes Multiple-Echo, Echo-Echo, and Single-Echo modes to handle coated, corroded, and uncoated surfaces.
- Depth Sensor & Live Depth Display — Provides real-time depth information during measurements.
- Live A-Scan Visualization — A-Scan waveform display assists in verifying measurement quality underwater.
- Deep Coat Function — Ignores protective coatings (e.g., paint or marine growth) to deliver true metal thickness readings.
- Simple, Intuitive Operation — Easy navigation with minimal function keys and a user-friendly menu.
- Comprehensive Data Logging — Stores data in linear and grid formats with optional real-time clock tagging.
- Rugged Subsea Durability — Designed for use in challenging underwater environments, rated for depths typically up to around 300 m.
