Cygnus Underwater Diver-Held Thickness Tester


  • Rp0



Designed for divers needing to take reliable thickness measurements of underwater structures, the Cygnus Underwater diver-held tester provides quick and accurate metal thickness measurements through coatings or even heavy corrosion

Specifically designed for divers undertaking ultrasonic thickness measurement (UTM) of underwater structures. The Cygnus Underwater diver held tester has been built to withstand harsh subsea environments while providing quick and accurate metal thickness measurements through coatings or heavy corrosion. This diver-held thickness tester is simple to operate using 3 function keys, an intuitive menu and a large LCD display – highly visible, even in low-visibility waters.

Key Features:

  • 3 measuring modes for levels of corrosion, various materials and through-coat measurements
  • Depth sensor – live depth display providing the diver with an accurate depth indicator
  • Live A-Scans aid visual measurement verification
  • Extremely Simple-to-Use with 3 function keys and up to 4 screens
  • Comprehensive data-logging: linear and grid
  • Deep Coat function ignores thick coatings
  • RTC (Real Time Clock) for tagging date/time on measurement points
  • Auto-set Gain to optimise the probe’s gain settings for optimal performance
  • Multiple Echo Mode to verify accurate through-coat measurements as specified by Class Societies
  • Measurement Stability Indicator (MSI™) verifies stable and therefore reliable measurements
  • Available in STD, PLUS and PRO variants with upgradeable options, e.g. Topside Repeating and Data Logging.
