With thousands of units being used throughout the world, the OmniScan® MX is a field-proven, reliable instrument that is built to withstand harsh and demanding inspection conditions. Compact and lightweight, its two Li-ion batteries provide up to 6 hours of manual or semi-automated inspection time.
The highly legible 8.4 in. (213 mm) real-time color display of the OmniScan MX enables you to see defects and details under any light conditions. Navigate your way through the instrument’s simple and intuitive interface using the scroll knob and function keys, or by connecting a USB mouse to facilitate the inspection analysis.
To meet the requirements of a broader range of applications, eddy current testing (ECT), eddy current array (ECA) and the new bond testing (BT) C-scan technology are available in two module versions. Both of these modules are compatible with the MXE (ECT/ECA) and MXB (BT C-scan) software, providing easy transition between technologies and a very short learning curve.
As with conventional eddy current technology, flaw severity is closely correlated to the return EC signal amplitude in most surface or near-surface applications. By using an amplitude-based color code, and plotting each channel’s return signal with encoded-position information, the resulting C-scan display is highly visual and intuitive. These scans can be saved to the removable CF card or generated into a report onboard the OmniScan® MX.
A reference standard with known depth defects is necessary to calibrate the sensitivity and contrast of ECA.

With the OmniScan MX ECA, you can accept or reject indications based on the C-scan color display. The MXE 3.0 ECA software contains a wide range of factory-tested color palettes that optimize the signal display for any ECA application.
Additionally, the new C-scan alarm feature simplifies the gating of reject signals, as it instantly changes the C-scan colors when the impedance plane signal enters the alarm zones.
