NEW Cygnus Underwater Diver-Held Thickness Gauge

Specifically designed for divers undertaking ultrasonic thickness measurement (UTM) of underwater structures. The Cygnus Underwater diver-held ultrasonic thickness gauge 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 gauge 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 of the NEW Cygnus Underwater diver held-gauge include:

  • 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.

NEW Cygnus 1 Ex Ultrasonic Thickness Gauge

Designed for taking reliable thickness measurements in Zone 0 Explosive Atmospheres, the Cygnus 1 Ex is certified intrinsically safe to ATEX, IECEx, UKEX for Zone 0 and NRTL for Class 1, Division 1.  The Cygnus 1 Ex boasts advanced data logging, manual measurement mode, features a large colour LCD display and offers 3 measuring modes for through-coat measurements and various materials - including heavily corroded metals.

Cygnus 2+ Hands Free Multi-Mode Ultrasonic Thickness Gauge

Perfectly suited for rope access and climbing applications, the Cygnus 2+ Hands Free UTG gauge offers the same as the standard Cygnus 2 with its end-mounted rotatable display, twin shot injection design and Multiple-Echo mode but also includes Single-Echo and Echo-Echo measuring modes for maximum versatility.

The Cygnus 2PLUS gauge still relies on Multiple-Echo to provide simple and accurate measurements, with the added benefit of Echo‑Echo and Single-Echo using twin crystal probes for extreme corrosion. Echo-Echo for measurements on painted metals but with heavy back wall corrosion / pitting and Single‑Echo for measurements on uncoated surfaces with heavy front face and/or back-wall corrosion and attenuative materials such as cast metals or plastics / composites.

Those required to perform non-destructive inspections of high structures such as bridges, offshore structures, storage tanks, etc using ropes to work at height will find the Cygnus 2PLUS UT thickness gauge a useful tool to have.
