Cygnus 1 Intrinsically Safe

The NEW Cygnus 6 PLUS ultrasonic thickness gage 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 3/4" (20 mm) thick;
  • 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 backwall 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 which 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.

Cygnus Probes and Cables

Stainless Steel INOX Single Crystal Probes

The INOX probes have an updated ergonomic design and an easier to read frequency, identification and serial numbering. All frequencies of INOX probes have a black face and a color coding ring to identify probe frequencies.

Used in Multiple-Echo mode, these probes require no zeroing, have a high linear accuracy, are ideal for general thickness gaging and on pipes and have replaceable wear membrane for long life.

Stainless Steel INOX Twin Crystal Probes

Used in Echo-Echo and Single-Echo modes and focused ultrasound beam with improved measurability on extreme back wall corrosion and pitting.

Cygnus Cables

Using standard industry connectors the probe lead uses a custom made over molded cable that offers superior flexibility and resistance to oils and ultraviolet light. The cable will not stiffen after exposure to ultraviolet light.

Flexible Handling

Along with the wrist and neck straps supplied in the kit there is also an optional belt clip, offering a range of flexible handling solutions for all types of applications.
