Nortec 700 Eddy Current Array Flaw Detector

Nortec 700 Eddy Current Array Flaw Detector

The NORTEC™ 700 from Evident is a portable eddy current testing (ECT) and eddy current array (ECA) flaw detector designed primarily for aerospace, MRO, defense, industrial, and manufacturing inspections. It combines conventional eddy current inspection with advanced array capabilities on a single platform.

Key features

• ECT and ECA in one instrument
• ECA probes with up to 256 channels on the new-generation probe technology
• High-resolution C-scan and C-scan waterfall imaging
• Surface and subsurface crack detection
• Bolt-hole and critical-hole inspection
• Dual-frequency inspection on N700D/N700i
• Conductivity and non-conductive coating-thickness measurement
• Automatic layer detection on the N700i
• 7-inch high-brightness display
• 30 kHz maximum measurement/sample rate
• IP65 environmental protection
• Operating temperature of −10°C to 50°C
• USB-C, Wi-Fi/Bluetooth and I/O connectivity
• Supports conventional absolute/differential probes and NORTEC PowerLink probes.

Typical applications

Aerospace

• Fastener-hole crack inspection
• Aircraft skin and structural inspection
• Surface and subsurface crack detection
• Multi-layer structure inspection
• Corrosion-related inspections

Industrial/manufacturing

• Metal surface crack detection
• Weld and component inspection
• Conductivity measurement
• Coating-thickness measurement
• Automated or semi-automated ECA scanning

Why ECA is useful

Conventional ECT generally uses a single probe/coil and produces a signal that the operator interprets. Eddy Current Array uses multiple sensing elements, allowing a larger inspection area to be covered and producing an image such as a C-scan. This can make defect location and interpretation more intuitive and can improve inspection productivity.
