    The prisma is the latest product from Sonatest’s technician focussed product development and research. An advanced ultrasonic flaw detector offering the technician an extremely comprehensive tool for test and measurement, which can be upgraded to include TOFD and Phased Array capability. An upgrade can be carried out wherever you are, there is no need to return the instrument, eliminating any downtime.


    Simple controls, superior performance, advanced features and a rugged enclosure deliver simplicity, capability and reliability to the technician’s finger tips.


    With the best display size and resolution in it’s category, the prisma provides the end user with an intuitive and workflow driven interface, excellent imaging capability uses the Full screen mode allowing 100% of the display to be used for Scan Imaging. Numerous palettes are accessible for all scan types “see things how you want to”, in amplitude or depth C-Scans, customise your palettes. Take full advantage of the advanced display modes which include smoothing, contouring and averaging all available to enhance your signal quality.


    The prisma is constructed to exacting standards using a rigid, shock mounted, internal chassis surrounded by an impact absorbing enclosure and designed to meet IP66; which ensures the unit is fully sealed against fine dust and jets of water.


    Typical applications are broad but include Weld Inspection, Corrosion Mapping, Aerospace and Composite Testing.
