The Cygnus 4PLUS is a small and tough multi-mode ultrasonic thickness gauge which features an A-scan display, simple to use sequential data logging and manual and automatic gain control.
Designed for the harshest of environments, with a simple to use keypad, intuitive menus and a colour LCD display which can be viewed in all lighting conditions.
The twin shot injection moulded enclosure has a soft but durable TPE outer skin which is comfortable to hold and protects against bumps while the hard internal shell offers maximum strength and environmental protection certified to the demanding US MIL STD 810G standard.
The unit 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.

Cygnus Probes and Cables
Cygnus Stainless Steel INOX Probes (Single Crystal Probes)
The INOX probes have an updated ergonomic design and easier to read frequency, identification and serial number. All frequencies of INOX probes have a black face and a colour coding system to identify probe frequencies. Used in Multiple-Echo mode, these probes require no zeroing, have a high linear accuracy, are ideal for general thickness gauging, for use on pipes and have replaceable wear membrane for long life.
Cygnus Stainless Steel INOX Probes (Twin Crystal Probes)
Used in Echo-Echo and Single-Echo modes for a focussed ultrasound beam for improved measurability on extreme back wall corrosion and pitting.
Using standard industry connectors the probe lead uses a custom made over moulded cable that offers superior flexibility and resistance to oils and ultraviolet light. The cable will not stiffen after exposure to ultraviolet light.
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.
