Product Description


TOFD-400 Ultrasonic Flaw Detector,TOFD technique is to use the work of a new ultrasonic non-destructive testing equipment. It is the high rate of detection of defects in quantitative high positioning accuracy, detection is simple and quick detection efficiency.

With intelligence operations, "one button TOFD" scanning to enable beginners to quickly master, unique touch-screen controls, buttons and the mouse can be used simultaneously, Shuttle controls can be a shuttle in the end, the operation is extremely simple, is the most compact "TOFD" flaw detector, including the battery weighs only 2.25 kg.


Main Features:
  1. "One button TOFD" scanning, so that TOFD testing more easier.
  2. Unique touch-screen controls, buttons and the mouse can be used simultaneously, Shuttle controls can be a shuttle in the end, the operation is extremely simple.
  3. The most compact "TOFD" flaw detector, weighing only 2.25 kg with battery
  4. Real-time help tips, ultrasonic flaw detection wave diffraction to solve the traditional single-scan detection limits of the region and non-intuitive.
  5. high-brightness high-resolution true color LCD touch screen.
  6. USB, LAN, SVGA output interface.
  7. Built-in probe position encoder.
  8. large-capacity data storage space.
  9. with A scan, B scan, D-scan and TOFD imaging capabilities.
  10. Real-time A-scan waveform display debugging the instrument is more fast and accurate.
  11. A scan waveform and B, D scanning image synchronized display, so that scanning is more intuitive.
  12. This machine scanning browsing records, and can playback A scan waveform.
  13. Defect size, location and type of accurate analysis.
  14. Manually configure the user-friendly and efficient scanning frame, portable scanning devices instead of manually scanning, detection faster and more accurate.
