The Cygnus 2PLUS is a simple to use, multi-mode thickness gauge having Multiple-Echo, Echo-Echo and Single-Echo capabilities. The NEW high durability end-mounted rotatable LCD display makes it ideally suited for climbing and rope access.
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.
Perfect for use on flat plate, curved surfaces or pipes our Multiple-Echo single crystal probe technology means you can measure through thick coatings and only the remaining metal thickness is displayed.
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 Instruments builds all of its equipment in the UK using only genuine and original parts and components – including Lemo® Connectors and Peli® Cases.

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 colour coding ring to identify probe frequency.
Used in Multiple-Echo mode, these probes require no zeroing, have a high linear accuracy, are ideal for general thickness gauging 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 focussed ultrasound beam with improved measurability on extreme back wall corrosion and pitting.
For optimum performance of the ultrasonic thickness gauge it is essential to utilise the appropriate probe for the specific material being tested. Here below are the probe options available.
|Single Crystal Probes:||6 mm – 5 MHz (S5A)|
|13 mm – 2.25 MHz (S2C (standard)), 3.5 MHz (S3C) or 5 MHz (S5C)|
|19 mm – 2.25 MHz (S2D)|
|Twin Crystal Probes:||5 mm – 7.5 MHz (T7A)|
|8 mm – 5 MHz (T5B (standard))|
|12 mm – 2 MHz (T2C (for attenuative materials such as cast metals, plastics and composites))|
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.
