Specifically designed for underwater remotely operated vehicles, Cygnus offers a dedicated ROV mountable thickness gauge (depth rated to 3,000m) with live A-scan and piezo-composite probe. This gauge is versatile and designed to measure metal thickness in the harshest subsea operating conditions – without the need to remove coatings. Ideal for use in Class surveys on offshore installations or units, subsea inspection, repair and maintenance (IRM) of infrastructure, underwater equipment.

Key Features:

  • A-scan to assist with measurement verification visually
  • Multiple-Echo and Echo-Echo modes for accurate measurements through coatings (up to 1mm) as specified by Classification Societies
  • Single-Echo mode for heavily corroded metals with no coating
  • Use the Auto SE/EE/ME measuring mode for best results or set manually
  • Supplied with CygLink software to display and process measurements on a computer at the surface
  • High-performance SD2C probe fitted with a Hard Rexolite Delay line
  • Easy calibration and measurement settings via CygLink software at the surface
  • P50 Probe Handler cleverly-designed to self-align with pipes from 50mm diameters to flat surfaces
  • Manual or automatic gain control.
