1. Chinese touch keyboard, intuitive and easy to remember, full Chinese tip and graphics display of operating process, can be mastered after simple training.

2. Automatic instrument and probe performance measurement are automatic, instrument calibration isautomatic, can measure thickness and material sound velocity.

3. Ten independent flaw detecting channels (electronic switch)

4. According to actual workpiece (e.g., weld, forgings, castings, tubes and pipes, sheet material, axle, wheel, small pipe diameter, etc.) to generate a custom flaw detection process, no need test block for on-site flaw detection.

5. DAC, AVG, dB DAC Curve are automatically generated, sampling pointsare not restricted, can be compensated and corrected, curve is automatic floating with gain, automatic extension with sonic path distance.

6. Real-time display offlaw echoes (horizontal, vertical, distance, dB equivalent value), and weld profile display.

7. Advancing wave door, wave loss door, DAC voice alarm, door position, door width and door height can be adjusted.

8. Peak memory, envelope function, more easily for searching the highest waveform.

9. Storage of 500 flaw detection data

10. Using new low reflective5.5″EL flat panel display (color TFT display), with features of strong resistance to electromagnetic interference, high contrast, and high resolution.

11. Voice alarm for low voltage, automatic shutdown protection.

12. Light weight (battery weight is only 1.6 Kg), small volume (dimension of 260×140×55), easy to use and to carry.

13. Using imported Nimh batteries, automatic protective charging (18 VDC, 220VAC) and can continuous working for more than 6 hours.

14. Can be normal working at -20℃~50℃.
