Digital ultrasonic flaw detector is advanced type, which is touch screen, can quickly, easily and without damage, accurately detect, locate, evaluate and diagnose various defects inside the work-piece such as cracks, welds, pores, sand holes, inclusions, folding, etc. It has been applied for electric power, petrochemical, boiler and pressure vessel, steel structure, military, aerospace, railway transportation, automobile, machinery and other fields. It is an essential instrument for the non-destructive testing industry.

1. High-precision quantification and positioning to meet the requirements of near and far distance detection
2. The near-field blind zone is small, can meet the detecting requirements for small-diameter and thin-walled pipe.
3. Auto calibration function: one-button auto calibration,easy to operate, automatic test probe "P Delay","K value","X value" and the velocity
4. Automatic display the defect echo position(Depth: d, Horizontal: p,Distance: s, Amplitude,dB,ф )
5. Switch three scales freely(Depth: d, Horizontal: p,Distance: s)
6. Auto gain, peak envelope, peak memory functions, which can improve the detection efficiency.
7. Automatically record the flaw detection process and dynamic playback
8. φ value calculation:  Forging flaw detection by straight probe, can find the highest wave to conversion φ value automatically
9. 500 independent channels(can be expandable), which can input and store the detection standards of any industries freely, do not need to carry the standard blocks for on-site inspection.
10. Store, playback 500 A-scan waves and data freely
11. The DAC, AVG, and TCG curves (depth compensationare automatically generated and can be segmented. 12. The sampling points are unrestricted and can be corrected and compensated.
13.  14 built-in inspection standards
14. Free to enter any industry standards
15. Pulse width and strength can adjustable
16. B scan and B color scan function;
17. Can communicate with the computer, and export WORD. File, also the detection report
18. IP65 ABS plastic case, sturdy and durable,water-proof and dust-proof, and excellent anti-interference ability
19. Use (wirelesscommunication software to analyze data print reports, etc;
20. 260,000-color true color screen, is suitable for working environment under strong light or low light
21. High performance lithium battery, can work continuously for 8-10 hours
22. Real-time clock recording: real-time flaw detection date, time tracking record, and storage
23. Power-down protection, storage data can not lost
24. Flaw detection parameters can be automatically tested or preset
25. Digital reject, does not affect gain and linearity
26. Gain compensation: Db attenuation can be corrected for surface roughness, curved surfaces, long-range flaw detection of thick work-pieces, etc.
27. Can operate the flaw detector by software at the PC, achieving the goal of computer-controlled flaw detector to detecting
