GEKKO


 

PHASED-ARRAY FLAW DETECTOR

 

With a 64-channel parallel architecture, GEKKO is the only flaw detector offering at the same time conventional UT, standard PAUT, TOFD and real-time Total Focusing Method (TFM). Some procedures require standard UT, others TOFD or PA. GEKKO includes all these techniques.

- 64:64 parallel channels

- + 4 additional TOFD

- Conventional UT channels

- International code compliance: ASME, AWS, API, ASTM, ISO-EN

2PA+TOFD

 

 

ADVANCED FEATURES

 

Gekko is the first portable phased-array flaw detector capable of driving matrix arrays and to perform Total Focusing Methods (TFM) in real time. With state-of-the-art hardware and software, Gekko provides unique features and will continue to improve to follow specification evolutions.

- Real-time and Adaptive TFM

- Linear, Matrix and Dual arrays

- 3 axis management

- 3D imaging

- Cylindrical reconstruction

 

USER-FRIENDLY

 

GEKKO software has been developed for all-level operators. The step-by-step interface is intuitive and simplifies the menus to reduce the risk for errors.
