RELIABLE ULTRASONIC MEASUREMENT CYGNUS 4+ GENERAL PURPOSE ULTRASONIC THICKNESS GAUGE The Cygnus 4+ General Purpose thickness gauge is a light, tough multi-mode thickness gauge. It features a sunlight readable display with Live A-scan, intuitive menu and sequential data logging for easy reporting and analysis. Used with Cygnus High Temperature Probe, the Cygnus 4+ can measure remaining wall thickness of high-temperature, in-service assets without shutdown or isolation. IDEAL FOR USE IN OIL AND HIGH STORAGE GAS TEMPERATURE TANKS PIPES/ TUBES SHIP SURVEYS ...plant maintenance, civil engineering, ship inspections, oil and gas facilities. High-temperature, in-service thickness surveys across refining, oil and gas, energy and process sectors. WWW.CYGNUS-INSTRUMENTS.COM

Cygnus High Temp Probe T5B-MAUH (Twin Crystal) For use on hot surfaces up to 300oC. Measures remaining wall thickness from 1.5mm to 250mm - depending on temperature and material. No cooling period required - reducing inspection time and facilitating more effective measurement. Option to use a standard cable or a more robust, braided cable. BASIC DATA LOGGING • • Linear based data logging Auto-log feature Eight user-defined comments to attach to any measurement point Saves measurements and A-scans Records stored on SD card CygLink software used to transfer and manage data Standard Cable Braided...

CYGNUS 4+ GENERAL PURPOSE SPECIFICATION Feature Measuring Modes Multiple-Echo using 3 echoes to ignore coatings up to 20mm thick Echo-Echo using 2 echoes to ignore coatings up to 1mm thick Single-Echo using 1 echo Velocities from 1,000 - 9,000 m/s (0.0390 - 0.3543 in/us) ±0.05 mm (±0.002”) - in Multiple-Echo measurement mode, when calibrated and measuring the same material as calibrated on. ±0.1 mm (±0.004”) or 0.1% of thickness measurement whichever is the greatest - in Single-Echo & Echo-Echo measurement modes, when calibrated and measuring the same material as calibrated on.
