▸Description
TUD290 Ultrasonic Flaw Detector is a high-performance portable ultrasonic flaw detector engineered for precision Non-Destructive Testing (NDT) applications. Featuring a vibrant 640 × 480 VGA colour display with a high-speed 60 Hz refresh rate, it delivers clear, real-time waveform visualization for accurate defect evaluation. Equipped with an advanced square-wave pulser, 110 dB gain range, and comprehensive inspection functions including DAC curve analysis, pulse-echo, dual-element, and through-transmission testing modes, the TUD290 provides reliable detection of cracks, inclusions, porosity, laminations, and weld defects. Designed for demanding industrial environments, it is an ideal solution for weld inspection, casting evaluation, pressure vessel testing, structural integrity assessment, and general quality assurance applications.
