Product Information

For Flaw Detection, Thickness & Dimensional Measurement in Tube & Bar.

  • Versatile Ultrasonic tester with superior performance and versatile, intuitive operation.
  • For full inspection of tubes, pipes and bars, plate and weld.
  • Operate on or off line.
  • Upgrade and/or replace older ultrasonic testers.
  • Use with rotary, spin-the-tube, squirter and bubbler installations.
  • Vivid, real time, flicker free full color display of test signals, thresholds and settings.
  • Up to 32 independent channels in one instrument.
  • Model 6A is GE Qualified as of 9-6-16 for P3TF31 Class A & B, & P29TF82 Class A & B, typical requirements for nuclear and aerospace applications.


  • Flaw detection, thickness measurement, dimensional evaluation, eccentricity calculation, weld inspection and characterization.
  • Set up and control of all key test parameters on one screen with a click of the mouse or keyboard.
  • Thresholds can be moved by selecting and dragging on screen and a “Global” key allows parameters for several channels to be adjusted at once, or copied from one channel to another.
  • The chart screen shows strip charting and defect logging of all events, up to 32 channels or functional groups, in live or replay mode.
  • Full tracking of end suppression, defect marking capability, and customizable data retention are included
  • Use with MAC’s Echomac® Rotary Ultrasonic Transducer assembly as well as with other existing immersion, bubbler or squirter type and “spin the tube” installations
  • Can replace any commercial ultrasonic instrument in almost any application.
  • Includes extremely flexible tracking, sorting and recording functionality that enables very close end testing and normalized recording which compensates for the many inspection planes necessary in complex multi-transducer configurations.

For applications that do not require extreme dynamic gain response, the recently improved FD4e Echomac® can be a viable lower priced option.  FD4e can be a modern, economical alternative for many everyday UT applications.  The FD4e utilizes a spike pulser, but has fixed FPGA functionality.
