USM 36 -

The Krautkramer USM 36 is the latest development in GE’s USM range of flaw detectors. It combines the 21st century operating platform with the reliable and robust hardware of GE’s well-established Krautkramer portable flaw detection instruments. It incorporates a range of innovative features to ensure that this new instrument is adopted as the everyday workhorse of flaw detectors by NDT inspectors globally.

  • Simple and efficient operation
  • Flexible data reporting and storage
  • Usable in harsh and industrial inviroments
  • Max allowable operating temperature range from -10°C to 55°

Available in three versions:

The versatile instrument is offered in three versions to meet the most standard inspection codes. The most advanced version can operate in DAC, AWS and DGS modes, features a powerful square wave pulser for excellent material penetration and can accommodate GE’s patented trueDGS probe technology, which offers unrivalled accuracy in sizing of flaws using the DGS method, as well the patented Phantom Echo Detection technology.
