Cygnus 6+ - CYG-050-6500-S2C-T5B General Purpose Multi-Mode Ultrasonic Thickness Gauge includes probes and leads


Product Description


  • Multiple-Echo for reliable, accurate through coating measurements
  • Single-Echo and Echo-Echo measuring modes
  • Large bright color LCD screen with automatic LCD back light
  • Min / max measurement limit functions with visual and vibrate alert
  • Extremely rugged enclosure - shock and impact to MIL STD 810G
  • Environment sealing to IP67 - MIL STD810G
  • Deep-coat mode, measures through coatings up to 20 mm (¾") thick
  • Cygnus echo-strength bars assist thickness measurements in Multiple-Echo mode
  • TPE over molded enclosure
  • Buttons designed for minimum of 100,000 depressions
  • Fully sealed battery compartment (contains any leaking battery fluids)
  • A-scan display
  • MSI™ (Measurement Stability Indicator) for Single-Echo and Echo-Echo modes
  • Sequential data logging
  • Automatic probe recognition for S2C and twin crystal probes

Multi-Measuring Mode:

  • Multiple-Echo uses three back wall echoes and measures remaining metal thickness while ignoring coatings. All measurements are error checked using 3 return echoes to give repeatable, reliable results. Accepted by all major classification societies. Uses single crystal probes for linear accuracy (and no probe zero required).
  • Echo-Echo uses two back wall echoes and measures remaining metal thickness while ignoring coatings up to 1 mm (0.04") thick using twin crystal probes for improved detection of back wall corrosion and pitting.
  • Single-Echo uses one back wall echo, measures remaining metal thickness on uncoated surfaces and is possibly helpful for areas with extreme front face or back wall corrosion and pitting. Effective on highly attenuative materials such as cast metals, plastics and composites.

MSI™ (Measurement Stability Indicator):

  • This clever technique helps ensure only stable measurements are displayed in Echo-Echo and Single-Echo modes. Displayed measurements change color from red to green and vibrate alert to indicate a stable reading.
  • Only available when using a twin probe.

Data Logging:

  • Comprehensive data logging
  • 5,000 measurement points (including A-scan) per record (soft limit of 100 records accessible from the gauge)
  • 3 options for logging; Linear, Grid (16 directional options) and Templates (created to by the user)
  • Choose from 8 user defined text comments to add to any measurement point
  • Add up to 12 additional ‘radial’ measurement points around the last logged measurement point
  • Easy to manage with functions to: step back; retake-last; stop and resume logging; review measurements; protect and delete records
  • Data logging screen shows average, highest and lowest measurement values in the whole record
  • Optional minimum and reference thickness values can be set and highlight logged measurements, i.e. red if under min. and green if between min. and ref.
  • AutoLog feature can automatically log thickness measurements without pressing a button, for hands free convenience
  • Records are easily transferred to a computer via USB lead or Bluetooth
  • The data is uploaded into CygLink software.

Cyglink Software:

  • CygLink is a Windows® application which is used to transfer information from the Cygnus 4+ thickness gauge to a computer. The information can then be used to create reports which can be analyzed, stored and exported.
