The WP2 allows the operator to build the most efficient solutions for scanning large areas of composites.  As the best alternative to immersion inspection, the WP2 offers an impressive 1 mm near surface resolution in the latest composite materials using 5 MHz array.

Composite Inspection:

Available also with 10 MHz, 3.5 MHz version, the WP2 tightly matches the acoustic impedance of water and, like its predecessor, generates UT signals of exceptional quality.  The configurable handles, adjustable laser guidance, unique LED’s for alarm feedback, remote control with start/stop indexing and reset buttons, as well as the remote display, makes this package unique, superior and still unequaled!

Corrosion Monitoring:

Making complete and reliable surveys to generate corrosion maps is more than a trend;  It is essential!  With the efficiency, performance and precision provided by the WP2, it is now possible to inspect large areas and quickly analyse data to determine if any critical or urgent action is required.  Moreover, this technique allows the user to compare large amounts of data over time to perform preventative maintenance, reducing potential downtime.  With the WP2, the level of confidence is significantly increased since decisions can be based on data sets that are 1000 times more detailed, yet still gathered in the same time needed to do ‘spot checks’ using traditional methods.  Whether for axial or longitudinal  inspection using unique grooved rollers, or attached to a scanner, WP2’s flexibility makes it the tool of choice for fast and accurate corrosion monitoring applications.
