NORTEC 700 Eddy Current Array Flaw Detector
In one seamless platform, the NORTEC™ 700 brings conventional ECT and advanced ECA within easy reach. A new generation of powerful probe technology and high-fidelity imaging deliver user-friendly dual-frequency and bolt-hole capabilities, shortening learning curves and making inspection more cost-effective than ever. Engineered from real-world input, this is a breakthrough that standardizes premium inspection technology.
NORTEC 700 Eddy Current Array Flaw Detector: Simplicity Built Around You
An accessible, unified eddy current solution, the NORTEC™ 700 eddy current array flaw detector pairs easy controls with next-gen probe technology and high-fidelity imaging so teams of all sizes can get up to speed fast and work with confidence through the most demanding conditions. Smart, scalable, and cost-effective, the NORTEC 700 eddy current array flaw detector is available in three operator-friendly models:
N700: Conventional eddy current (ECT) for single-frequency inspections
N700D: Expanded versatility with enhanced dual-frequency and bolt-hole capabilities
N700i: Both ECT and advanced eddy current array (ECA), and layer detection
Based on the proven NORTEC 600 series, all three models share the same user-friendly build, simplified workflows, and digital ecosystem compatibility, ensuring seamless training and easy fleet standardization.

Applications
Aerospace
Engineered to deliver exceptional performance for aerospace applications, the NORTEC 700 allows quick, easy surface, wheel, and bolt-hole inspections. The NORTEC 700 offers the signal quality, versatility, and confidence you need to meet every demand of critical aerospace inspection, from surface cracks to fasteners to layered structures.
Defense
Within the harshest conditions on earth, the NORTEC 700 is a mission-ready inspection tool built to keep up. From surface crack detection to bolt-hole and fastener inspection, the NORTEC 700 helps maintenance teams stay on top of aircraft, ground vehicles, naval vessels, and critical equipment through long shifts and remote deployments.
Industrial
The NORTEC 700 gives industrial inspection teams the signal quality, ruggedness, and flexibility to detect flaws accurately and efficiently, wherever the job takes them. The NORTEC 700 is ideally suited for weld inspection and surface and corrosion inspection across a wide range of industrial components and materials
Surface/Subsurface Inspection (N700, N700D, N700i)
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.
Conductivity & Coating Thickness Measurement (N700, N700D, N700i)
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.
Critical Hole Inspection (N700D, N700i)
With the NORTEC 700, inspecting critical holes is simple and reliable. With support for most industry bolt-hole scanners, improved C-scan waterfall display, and layer cursor, the NORTEC 700 easily pinpoints the location of flaws in layered structures. In addition to these features, the N700i model includes layer detection, a Defect Viewer, and a C-scan view.
Dual-Frequency Inspection (N700D, N700i)
All-in-One Display
An all-in-one display features up to three configurable traces for frequency 1, frequency 2, and mixed channels. Each channel can be displayed as an impedance or strip chart, with independent display position controls.
Real-Time Readings
With the Real-Time Readings parameter, you can choose to display up to two real-time signal measurements in standard or full-screen modes. Displaying a variety of measurements reveals the various amplitude and angle (phase) characteristics of the signal.
Choice of three peak-to-peak amplitude measurements (horizontal, vertical, or magnitude)
Horizontal or vertical maximum distance from null point
Angle (phase) measurement of signal as peak-to-peak
Weld Inspection (N700, N700D, N700i)
Thanks to its portable, rugged design, the NORTEC 700 eddy current array flaw detector is ideally suited for weld inspection in extreme environments.
