CYGNUS 2+ HANDS FREE

Description

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.

Features

Multiple-Echo for reliable, accurate through coating measurements as specified by Classification Societies

Cygnus Multiple Echo Technology

With multiple echo technology, readings are taken by measuring the time delay between any three consecutive backwall echoes. The time T1 (for coating thickness) is ignored. The times T2 and T3 are equal to the time that it takes for sound to travel through the metal. Only by looking at three echoes can the measurements be made for the metal thickness, where T2 = T3.
