A compact, hands-free ultrasonic thickness gauge with an end-mounted display – perfect for rope access and climbing inspections across corroded or coated assets.
Read More

The Cygnus 2+ is purpose-built for rope access, climbing inspections, and hands-free operation in tight or elevated spaces. With its end-mounted screen, thickness readings can be viewed at a glance, whether mounted on the wrist, waist, or harness.

Equipped with Multiple-Echo, Echo-Echo, and Single-Echo modes, it can measure through thick coatings, detect corrosion, and handle a wide range of materials including metals and plastics. The rugged IP67-rated housing and MIL STD 810G certification ensure it stands up to the harshest field conditions, from marine structures and ship hulls to civil infrastructure and plant maintenance.

An intuitive interface, Measurement Stability Indicator, and deep coat function enhance usability and accuracy, while upgrade options (4+ or 6+ variants) allow you to scale capabilities as needed.
