TOFD-400 Ultrasonic Flaw Detector,TOFD technique is to use the work of a new ultrasonic non-destructive testing equipment. It is the high rate of detection of defects in quantitative high positioning accuracy, detection is simple and quick detection efficiency.
With intelligence operations, "one button TOFD" scanning to enable beginners to quickly master, unique touch-screen controls, buttons and the mouse can be used simultaneously, Shuttle controls can be a shuttle in the end, the operation is extremely simple, is the most compact "TOFD" flaw detector, including the battery weighs only 2.25 kg.
