  • TFM 3D real-time imaging. 
  • Up to 6 TFM modes at one time.
  • Support TFM image resolution 1024x1024 & raw FMC data recorded.  
  • 64 channel PAUT with higher sensitivity and SNR, ideal for ≥100mm thick welds.


  • Fitting Curve Algorithm in TFM (Published patent)
  • Free selection of TFM image resolution and support up to 1024x1024.
  • TFM 3D real-time imaging, with higher resolution & more intuitive results.
  • Up to 6 propagation modes can be displayed simultaneously to better identify and size flaws.
SyncScan 2

SyncScan 2 is a 32:128PR PAUT flaw detector with an optional 2-ch TOFD, which can improve your efficiency for PA and TOFD.


  • Light weight: 4kg only including battery.
