Ultrasonic flaw detector GDUD series

for NDTportable

GDUD-PBI Ultrasonic Flaw Detector for Electrical Equipment Ultrasonic Flaw Detector is a non-destructive testing device used for detecting internal mechanical damages for electrical equipment. Applications It detects internal flaws of electrical equipment, such as bushings, bus bars, wire clamps, transformer tank, current&voltage transformers, surge arresters, generator bearing equipment, and porcelain pillar type insulators, etc. Features TFT true color screen. High accuracy and wide applications. High sensitivity of flaw detection, up to 110db. Built-in standard curves and test block for pillar type insulators. The device alarms if internal crackle flaws are super-standard. Automatic calibrations for probe and curvature surface, which optimizes the coupling between the probe and test object and ensures accuracy. Aluminum alloy chassis, which has excellent anti-interference performance. Low noise and high signal-to-noise ratio.
