NDT AFD 150 Universal Ultrasonic Flaw Detector


The AFD150 combines the powerful advantages of digital design with the detailed dynamic echo information that was previously only possible with an analog display. The high resolution colour LCD display, 150 Hz update rate, and “single shot” measurement technique produces a fast, smooth response for immersion and critical weld testing. The durability, ease of use and reliability of the AFD150 means that it is equally well equipped for rugged field testing to high resolution, high accuracy laboratory inspections as well as long acoustically clean materials and immersion systems work. The AFD150 extends the range of applications that a portable instrument can perform. 12 hours of battery use, easy key operation, outstanding ultrasonic performance and now “square wave pulser” and “colour leg” combine to form a powerful portable ultrasonic inspection tool with a long battery life.
