CX-DUFD-520/521/522 Digital Ultrasonic Flaw Detector
Summarize:
  Ultrasonic flaw detector is a portable industrial nondestructive flaw detector, it can be rapid, portable, no damage, accurately to defect, locate, eva luate and diagnose in workpiece internal of a variety of defect (cracks, porosity, porosity, inclusion, etc.). Can be used in laboratory, and can also be used in engineering field. Widely used in boiler, pressure container, aerospace, electric power, oil, chemical, marine oil, pipelines, military industry, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing, steel structure, railway transport, nuclear power, universities, etc.
 
Main functions:
●Use standard test block automatically generated DAC, AVG curve;
●Automatic gain, echo envelope function to improve the detection efficiency;
●Two input mode: angle probe angles and K value;
●Automatic display echo related parameters (depth D, level P, distance S, amplitude, H);
●Automatically calculate defect value φvalue;
●Free switch three scaleplate (depth D, level P, distance S);
●Free enter and store any industry inspection standard (according to user requirements extension);
●Straight insert USB interface, unlimited recording testing process;
●Lithium battery, can work continuously for 10 hours;
●Big screen highlighting display, can meet the needs of the flaw detection in the sunlight, culverts.
