Reinventing High-definition Portable UT

Pioneering real-time TFM since 2013, Gekko innovation keeps being driven by market applications. Used in accredited training centers and ready for TFM standards, it benefits from advanced algorithms through a streamlined software user interface (Capture). Simply powerful, Gekko brings the latest technology at your fingertips.

Built for All-level UT Inspectors

With continuously added tools in one standalone application, Capture eases the inspection process and reduces operator errors. Without the need to use third-party software to load basic and advanced procedures, all-level UT inspectors have access to performance through a visual and guided interface. Capture offers a quick way to improve PAUT knowledge and requires minimum training for phased array inspectors.

Designed for the Field

Gekko, the #1 PAUT unit with Total Focusing Method (TFM), has been upgraded based on inspectors' feedback. Offering both conventional UT, TOFD and advanced PAUT, Gekko is the most versatile unit adapted to field conditions

A Complete PAUT Portable Unit

Gekko includes all basics and advanced UT features in a reinforced compact casing designed for field use. It natively comes with conventional UT, TOFD and all beam-forming phased array UT techniques for single-beam and multi-group inspection and its 3-encoded axis capabilities make the Gekko ready for any challenging inspection. This rugged PAUT unit also offers real-time TFM/FMC (Full Matrix Capture) and Adaptive TFM techniques.

Portable & Robust

Bumpers and connectors are designed for robustness and accessories versatility. The bright resistive touch screen allows outdoor use in rough conditions. Powered by 2 hot-swappable batteries, Gekko now reaches up to 6 hours of autonomy and becomes the ultimate reference in its product range.

Compatible With Most Accessories

Coming with an IPEX type PA connector and a LEMO16 encoder, Gekko is compatible with Eddyfi® accessories and most probes and scanners on the market. For other configurations, Eddyfi can provide the adapter to ensure compatibility with your current accessory.

No Compromise on Performance

The innovative electronics offers up to 128 channels, great signal quality and TFM resolution for improved detection and confidence. It now reaches a high scan speed and productivity.

Fast Connectivity Solution

The connectivity solutions—dongle-activated Wi-Fi™, USB 3.0 connector and Gigabit Ethernet output—allow to speed up data transfer and to remotely control your inspection in challenging conditions (TeamViewer license included). Moreover, the 256 GB SSD makes the operator’s work very comfortable with unlimited data file size, thus saving time in the field.

Streamlined Workflow

Powered by Capture, the new generation Gekko has been designed to ease the setup process and save time for the inspectors operating in tough environments. The newly added onboard scan plan and analysis features join the popular 3-click wizards for evaluation of material velocities, amplitude balancing of the transducer, flat and curved wedge calibration, as well as the automated TCG. Enriched to offer an all-in-one inspection solution—from application design to inspection and reporting—Capture offers the latest phased array technologies in a couple of clicks.

Unique Features

  • Complete toolbox for TFM including TCG calibration
  • High-resolution TFM imaging up to 128 elements
  • 3-axis nozzle inspection with live overlay display
  • 3-axis paintbrush for composite and corrosion mapping
  • Live display of fillet weld inspection
  • Real-time Adaptive TFM (ATFM) for inspection of wavy surfaces

How to simplify welds NDT inspection using Total Focusing Method (TFM) and Phased Array UT (PAUT)

Girth-weld inspections require numerous parameters to be specified on most flaw detectors. The Gekko and its user interface (Capture) solve these challenges. Using off-the-shelf probes, the NDT inspector can quickly configure his 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 (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
