Eddy Current Flaw Detectors


The new NORTEC 600™ incorporates the latest advancements in high-performance eddy current flaw detection into a compact, durable unit. With its vibrant 5.7-inch VGA color display and true full-screen mode, the NORTEC 600 produces user-selectable, high-contrast eddy current signals.

Probes for Tube Inspection

These probes for tube inspection are lightweight but solidly constructed and use eddy current, remote field, magnetic flux leakage, and IRIS ultrasound technologies. These probes are used for ferromagnetic or non-ferromagnetic tube inspection applications.


The OmniScan™ MX ECA/ECT flaw detector is used to perform eddy current array testing inspections. The test configuration supports 32 sensor coils (up to 64 with an external multiplexer) working in bridge or transmit-receive mode. The operating frequency ranges from 20 Hz to 6 MHz with the option of using multiple frequencies in the same acquisition.

Bolthole Scanners

Rotating Bolthole Scanners

Our high-performance eddy current bolt hole scanners are available for use with NORTEC eddy current flaw detectors. Features include speed ranges from 600 to 3000 rpm, frequency ranges from 100 Hz to 6 MHz, multiple connector types, and multiple probe types.

Eddy Current Testing Equipment FAQs

How does eddy current measurement work?

Eddy current testing is a nondestructive testing (NDT) method that can be used for various inspection and detection applications. Eddy current inspections work using an electromagnetic field to measure the response from a material. Eddy current testing equipment generates magnetic fields, which induce a current that flows in a test piece (e.g., a conductor such as a coil). This influences the magnetic field, as well as the magnitude and phase of voltage in the coil. Any changes in conductivity, such as defects or thickness differences, can affect the resulting eddy current. This technology can then be used to measure distance or to detect flaws in conducting materials such as corrosion, erosion, wear, pitting, baffle cuts, wall loss, and cracks.
