Combined ECT and ECA

The NORTEC 700i combines conventional eddy current testing (ECT) and advanced eddy current array (ECA) capabilities in one instrument. Seamless switching between modes eliminates the need for reconfiguration.

Intuitive Interface and Simplified Navigation

The NORTEC 700 features an intuitive interface with an updated navigation system. Its logical menu structure reduces the number of steps required to perform an inspection and makes it easier to switch between the instrument’s primary functions. Intelligent presets automatically load the appropriate parameters for the selected probe and inspection type, eliminating time-consuming manual setup and reducing preparation time to just a few seconds.

NORTEC 700 Functionality

Defect Viewer

The N700i configuration includes the Defect Viewer function, which displays defects at a 1:1 scale for easier comparison between the on-screen image and the actual defect size. For hole inspection, Direct Hole View mode works together with Minimite rotary scanner data to improve defect location accuracy.

Hole Inspection

The NORTEC 700 is optimized for hole inspection using a rotary scanner. An advanced filtering system and simplified setup reduce preparation time. By default, filters are set to "figure 6", as it is the most commonly used for this type of inspection. If required, "figure 8" can be selected. Filter parameters are automatically synchronized with the scanner’s rotation speed.

How NORTEC 700 works

The NORTEC 700 uses eddy current technology to detect surface and near-surface discontinuities without damaging the inspected part.

An alternating current flowing through the probe coil generates a high-frequency magnetic field. When the probe is placed near a conductive material, the field induces eddy currents within the component. Discontinuities disrupt the flow of eddy currents, causing changes in the probe's electrical impedance. The NORTEC 700 captures and processes these changes in real time.

Intelligent presets

Application-specific presets automatically configure key parameters for the selected probe and inspection type.

Signal Acquisition and Processing

The NORTEC 700 uses advanced digital signal processing to deliver stable, high-resolution eddy current measurements in real time.

Real-Time Visualization

A bright and clear display provides immediate visual feedback for on-site adjustments during inspection.

Data Handling

Results can be stored, reviewed, and transferred for reporting and further analysis, supporting traceable quality control workflows.

NORTEC 700 Applications

Surface and Subsurface Inspection

The NORTEC 700 includes all standard inspection functions: C-scan and impedance plane views, 10 × 10 grid, sweep (strip chart), multiple alarm setups, and automatic lift-off. It also provides null point crosshairs, fine (expanded) grids, web grids, and an automatic internal balance circuit (BNC connector).
