N700D: Expanded versatility with enhanced dual-frequency and bolt-hole capabilities
N700i: Both ECT and advanced eddy current array (ECA), and layer detection

Eddy Current Testing Easy from the Start

Streamlined controls, an intuitive interface, and a comfortable, lightweight design help you work faster, stay focused, and trust every result.

The NORTEC 700 offers:

A simplified navigation
Multiple test capabilities
Application-based Intelligent presets
Hybrid hard key/ touchscreen controls
Lightweight portability
Enhanced ergonomics

ECT and ECA in One Seamless Platform

The NORTEC 700 combines conventional ECT and advanced ECA in one platform. Users can transition effortlessly between ECT and ECA using the same intuitive interface, preserving setup continuity and eliminating the need for separate instruments.

Next Generation Eddy Current Array Probes

The NORTEC 700 platform introduces not only a new flaw detector, but an entirely new generation of eddy current array probes (up to 256 channels) delivering superior repeatability, uniform signal quality from probe to probe, and simple calibration.

Bolt-Hole Inspection and Layer Detection

Advanced automatic layer detection and Freeze Mode bring new precision to bolt-hole and multi-layer inspections.

Using intelligent signal interpretation, the N700i can accurately distinguish between fastener and backing material layers and genuine defect responses- reducing false calls and minimizing rework.

The Defect Viewer feature simplifies defect localization using the direct hole view and the Minimite scanner overlay image.

A New Standard in NDT Inspection

Equal parts simplicity and performance, the NORTEC 700 is available in three versatile models to meet inspection demands across an array of aerospace, defense, industrial, and manufacturing applications. Additional features can also be unlocked remotely.

Four Connectors

All NORTEC 700 models come with a standard LEMO® 16-pin universal connector, a BNC ECT connector (automatic internal balancing), an ECA connector, and an I/O connector (for system integration)-simply select the connector in the easy-use interface.

The NORTEC 700’s LEMO connector also supports POWERLINK NORTEC probe technology (for bolt-hole and conductivity inspections only), which features automatic probe recognition and instrument presets for quicker setups.

Exceptional Visual Clarity Keeps Inspections Moving

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.

Alarm and analog outputs, digital inputs
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.

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.
