Intelligent Portable Phased Array UT Instrument with Total Focusing Method Capabilities

Introducing the ultra-intelligent TOPAZ®64, a portable 64-channel phased array ultrasonic testing (PAUT) instrument delivering faster, more reliable inspections. It intelligently combines the power of 64 active channels for PAUT applications with the most advanced full matrix capture (FMC), total focusing method (TFM), and plane wave imaging (PWI) capabilities.



  • Phased array up to 64/128PR with 2 UT channels at 200V
  • FMC or PWI excitation with up to 64 elements
  • Real-time high-resolution TFM
  • 64-channel code compliant PAUT
  • Time-of-Flight-Diffraction (TOFD)
  • Raw FMC data saved in encoded mode
  • 307 mm(12.1 in) high-resolution multi-touch display
  • Maximum PRF of < 40 kHz


  • Code compliant inspections on thick welds
  • Corrosion mapping
  • Composite inspections
  • Complex component inspections

Inspection Intelligence

  • More UT power, TOPAZ64 offers a 64/128PR phased array UT configuration with two separate conventional UT channels at 200V
  • Multigroup setups for code-compliant inspections with multiple techniques including plane wave imaging (PWI), TFM, phased array and TOFD at the same time
  • High TFM resolution up to 1M points per frame
  • Fast TFM speed up to 110Hz for 65k points frame
  • New bipolar pulsers (150Vpp) provide more energy to penetrate through thick components
  • Save time and money by saving raw A-Scan data for record-keeping compliance or TFM post-processing without the need to rescan
  • Ideal for demanding environments thanks in part to a rugged, lightweight casing with no air intake.
