M2M GEKKO is the first phased-array ultrasound portable flaw detector capable of driving matrix arrays and perform Total Focusing Methods (TFM) in real-time. With state-of-the-art hardware and software, GEKKO provides unique features to answer the operator's needs and its NDT specifications.

GEKKO is field qualified in the oil & gas, nuclear, power generation, aerospace, and railway industries, and it meet the minimum instrumentation and software requirements specified by ASME, AWS, API, ASTM, and ISO. Furthermore, Gekko is certified by PCN and CSWIP.


• Gas tank inspection
• Pressure vessel inspection
• Hydrogen damage (HIC, HTHA)
• Nozzle inspection
• Corroded pipe inspection
• Turbine blade inspection
• Girth weld pipe inspection
• Aircraft inspection
• Rail inspection
• Multi-group weld inspection
• Etc.


Girth-weld inspections require numerous parameters to be specified on most flaw detectors. The GEKKO and its user interface Capture solve these challenges, significantly improving your work in a very easy way.

Using off-the-shelf probes, NDT inspectors can quickly configure a unit, scan and analyze the collected data with confidence.

In this webinar, you’ll learn:
• How fast Capture makes it easy to get ready to scan using ultrasonic techniques such as total focusing methods (TFM) and phased-array ultrasound (PAUT), how streamlined is the analysis of TFM data and how chosen approaches compare.
• How adding TFM to a PAUT unit overcome limitations of each technique.
• A case study: girth-weld inspection setup, data acquisition, and analysis overview.


M2M Gekko Phased array ultrasound flaw detector for NDT




With a 64-channel parallel architecture, GEKKO phased-array ultrasound flaw detector offers 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. This flaw detector includes all these techniques.

• 64:64 parallel channels

• + 4 additional TOFD

• Conventional UT channels

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


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.

• All-level operators

• Step-by-step applications

• Calibration wizards

• Analysis and reporting tools
