Ultrasonic Flaw Detector With Narrow Band Filters (SNR)

GAOTek ultrasonic flaw detector with echo envelop enables to detect the flaw and position located with anti-interference




GAOTek ultrasonic flaw detector with echo envelop enables to detect the flaw and position located with anti-interference

Key Features

  • Memory Key for storing, plug and play
  • Connecting with memory key direct, no need software, plug and play, helping you to get rid of cable.
  • Two-dimensional coding from scanning, the flaw will be showed directly.
  • X series UFD-5 has broken out the one dimensional wave, adopting two-dimensional coding fro scanning. This makes detecting easily, the result will be showed directly, this matter reduces ergo and missing, improving the speed for detecting.
  • Large Memory:3,200 data groups
  • Combining the flaw detector and high accuracy thickness measuring, economic and convenient.
  • Intelligent DAC curves, measured up to JIS and API standard.
  • Used DGS curve: Flat bottomed, flat-bottomed hole, through holes as references
