Evident offers portable eddy current equipment to meet a broad range of applications, including the detection of surface or near-surface defects and the inspection of bolt holes. Our eddy current testing equipment includes the latest advances in eddy current flaw detection for precise use in various inspection applications. In an eddy current inspection job, you need equipment you can trust. Our eddy current flaw detectors are built with endurance in mind and are field-proven to withstand even the most demanding conditions.

Eddy Current Flaw Detectors

NORTEC 600

The NORTEC 600™ instrument incorporates 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 flaw detector 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.

OmniScan MX ECA/ECT

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.

Rotating Bolthole Scanners

Our handheld rotating bolthole scanners work with our line of NORTEC eddy current flaw detectors for the inspection of fastener, bore, and bolt holes. Ideal for aircraft structural maintenance, our scanners help you find flaws fast with high-speed (up to 3000 rpm) and high-frequency (up to 6 MHz) eddy current testing. Boost productivity and comfort with handheld rotating scanners in right angle or ergonomic grip designs.

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.
