Phased-Array Ultrasonic Testing
(PAUT) Probe Ordering Guide


Our phased-array transducers have frequencies ranging from 1 MHz to 18 MHz and can have between 8 to 256 elements. Here is a list of some of the type of phased array transducers we manufacture:



• 1D linear array transducers
• Concave array transducers
• 2D matrix transducers
• Dual 1.5D matrix transducers.



NextNDT offers a complete line of wedges that complement its phased array ultrasonic transducers. Designed to tackle any applications, our wedges come equipped with irrigation channels and easy fixation points for simple interfacing with scanning mechanisms.
