The Cygnus 2+ Hands-Free is a rugged, flexible thickness gauge designed for truly hands-free operation. With its end-mounted display and three distinct measurement modes, it suits challenging applications — from severely corroded metal surfaces to plastics and engineering materials. Whether you’re working on ship hulls, rope access scenarios, or industrial plant assets, this meter is built to deliver reliable ultrasonic thickness measurement.
Three measuring modes: Multiple-Echo, Echo-Echo, and Single-Echo — covering coatings, corrosion, and a wide range of materials
Deep Coat function allows accurate measurements beneath coatings up to 20 mm (0.8″) thick
Measurement Stability Indicator (MSI) ensures steady, verified readings in Echo-Echo and Single-Echo modes
Hands-free mounting options — wearable on the wrist, waist belt, or harness — with an end-mounted display for immediate visibility
Rugged and reliable: sealed to IP67 for dust and water protection and tested to MIL-STD-810G for shock and impact resistance
Transducer flexibility: compatible with both Single-Crystal and Twin-Crystal probes to match different materials and inspection needs
Upgradeable design: can be field-upgraded to higher models such as the Cygnus 4+ or 6+ for expanded functionality
Ideal for rope access and climbing inspections, allowing safe, hands-free operation in difficult or elevated locations
Used for hull thickness and UTM inspections on ships, offshore platforms, and other marine structures
Suited for civil engineering and structural integrity assessments on bridges, tanks, and industrial assets
Accurately measures through coatings up to 20 mm (0.8″) without removing paint or protective layers
Performs reliably on heavily corroded metals with front or back wall pitting and irregular geometries
Effective on attenuative or challenging materials, maintaining stable readings even in harsh environments
