Brief introduction: GNU80 digital ultrasonic flaw detector is a portable intelligent enhanced digital ultrasonic flaw detector. It can fast, convenient and noninvasive and accurate artifacts within a variety of defects (cracks, inclusions, porosity, porosity, etc.). High reliability, good stability, can comprehensively and objectively to collect and store data, and the collected data in real time or after processing, the signal in time domain, frequency domain, or image analysis, to reduce the influence of artificial factors, improve the reliability and stability of the retrieval, truly achieve castings, forgings, plate, weld inspection easy! Widely used in aerospace, petrochemical, metallurgy, electric power, railway transportation, boiler, pressure vessel, steel structure, mechanical processing and other fields. Features: 1.100 independent inspection channels; 2. The square wave pulse amplitude and pulse width adjustable, suitable for different detection requirements; 3. Possess A flicking A and B two scanning way; 4. The DAC curve welding seam, DGS (AVG) curve suitable for forging workpiece inspection; Built-in all standard at home and abroad. 5. A peak inside the gate automatically capture function; And design a shortcut keys and digital shuttle spin round. 6. Has a straight probe, oblique probe automatic calibration function, use simple convenient; 7. Super bright display, light, low light environment, the sun can clear display; 8. FFT spectrum analysis function 9. Weld graphic, crack depth, aperture, surface modification, echo envelope, echo encoding 10. IP56 waterproof and oil design, probe interface protection, flexible probe line can be used into hours is not damaged. 11.
