The NORTEC 700 delivers exceptional visual clarity that helps you interpret results faster and with more confidence. Its high-brightness, high-resolution 7-inch display remains sharp and readable even in direct sunlight, ensuring consistent visibility whether indoors or on the tarmac. Enhanced color mapping and real-time imaging bring subsurface defects and surface cracks into sharp focus, delivering instantly recognizable patterns.
Every viewing element—from a responsive interface to refined contrast and brightness—was engineered to improve interpretation accuracy, reduce eye strain, and keep inspections simple and efficient.
Fast Layout Selection
With the NORTEC 700, it is easy to change the layout view using the Next Layout direct-access key. Layouts are user-selectable, enabling you to configure the display to best suit your inspection needs. Choose from a variety of displays:
Single impedance plane
Dual impedance plane
Sweep (strip chart)
One-to-one view
C-scan
C-scan waterfall
Split screen (sweep + impedance)
All-in-one display featuring up to three configurable traces
Seamless Eddy Current Integration
The NORTEC 700 merges seamlessly into any integrated eddy current detection system, ensuring consistent flaw detection in even the most demanding environments.

Standard impedance plane view, sweep mode (strip chart), C-scan, split screens, adjustable null point, crosshairs, improved filter response, reference signal display, and other useful features are all part of the NORTEC 700 package.
Simplified Reporting that Ensures Accuracy
The NORTEC 700 simplifies the entire reporting process with fast, reliable tools that document inspection results directly from the detector—no extra hardware, software, or complex data handling required.
You can capture and save inspection snapshots, setup parameters, and signal data, ensuring that every result is recorded accurately and ready for review.
Application-Based Intelligent Presets
The NORTEC 700 turns complex inspection setup into a guided, intuitive process. Each preset automatically configures key parameters for selected probes and inspection types, eliminating guesswork and reducing setup time to seconds.
With preconfigured setups, field crews can start inspections with minimal training knowing that parameters are already optimized for accuracy and compliance. This built-in intelligence ensures consistency across operators and shifts, enforces compliance, and dramatically reduces operator error.
Intuitive File Management
Easily preview, edit, overwrite, and delete files using the NORTEC 700’s File Manager menu. A file preview function makes it simple to browse through different files. Once a file is found, it can be recalled at your convenience. The onboard Text Editor makes it simple to edit file names, revise user and instrument information, and add notes while onsite.

The NORTEC 700 is ideally suited for weld inspection, heat exchanger and tube inspection, and surface and corrosion inspection across a wide range of industrial components and materials.
High-performance electronics and a vibrant display deliver outstanding signal quality for surface and subsurface inspections. All standard features for medium- to high-frequency inspection are included: impedance plane views, 10 × 10 grid, sweep (strip chart), multiple alarm configurations, and automatic lift-off. Added features include null point crosshairs, fine (expanded) and web grids, and automatic internal balance circuit (for BNC connector).
Bolt-Hole Inspection (N700D, N700i)
Simplified configuration and an improved filter system make the NORTEC 700 ideal for bolt-hole (rotary scanner) inspection. Filters are set by default to a “figure 6” response. The filters can also be set to the “figure 8” response as needed. For an even easier configuration, operators can activate the Link option, which automatically adjusts the filter settings according to the scanner’s speed settings.
The NORTEC 700’s conductivity mode features a straightforward calibration wizard including user-defined conductivity and coating thickness references. The NORTEC 700 can measure conductivity and non-conductive coating thicknesses of up to 0.64mm (0.025 in.) on non-ferromagnetic materials.
