Cygnus 6+ PRO Multi-Mode Ultrasonic Thickness Gauge

Pine Item #54844

The NEW Cygnus 6+ ultrasonic thickness gauge has a large front LCD color display plus an end mounted OLED display, offering maximum versatility.

The gage includes comprehensive data logging, A-Scan, and B-Scan display, automatic and manual gain control, and Bluetooth connection.

The instrument has three measurement modes:

  • Multiple-Echo to provide extremely accurate measurements while ignoring protective coatings up to 20 mm thick
  • Echo-Echo for measurements on painted metals but with heavy back wall corrosion/pitting
  • Single-Echo for measurements on uncoated surfaces with the heavy front face and/or back-wall corrosion and attenuative materials such as cast metals or plastics/composites.

Designed for the harshest of environments, with a simple to use keypad, intuitive menus, and a color LCD display that can be viewed in all lighting conditions.

The twin shot injection molded enclosure has a soft but durable TPE outer skin which is both comfortable and robust while the inner shell is strong, keeping the electronics totally sealed from the outside world. Having passed the stringent US Military Standard 810G environmental tests, this new housing represents toughness and reliability.
