All of Criterion NDT’s eddy current instruments are designed to identify defects on your critical automotive or medical components, in real-time on your production line.  Testing time is measured in seconds or fractions of a second, and integration with material handling systems is simplified using our eddy current instrument’s full industrial I/O capabilities.

CR-11 Eddy Current Test Instrument

Criterion NDT’s CR-11 single channel eddy current test instrument is specifically designed to find material defects such as cracks and flaws in components during production processes – in real-time. This helps you to quickly detect and separate flawed product, reducing scrap and warranty costs.

The CR-11 comes with a rugged, easy-to-use touch screen user interface which makes set up and operation quick and easy. Its rugged aluminum case and full industrial I/O make it perfect for on-line, industrial environments.



InSite HT and CT Eddy Current Instruments

The InSite HT and InSite CT are multi-channel, multi-frequency eddy current instruments. They are both designed to operate at full production line speeds in tough manufacturing environments. Both the InSite HT and InSite CT are available in 2, 4, and 8 channel versions.

The InSite HT eddy current instrument helps you to identify improper heat treatment conditions such as shallow case depth, short heat, misplaced case, delayed quench, short quench, air-cooled, or no heat treatment. The InSite HT can be used to test for proper heat treatment on simple parts such as ball bearings and fasteners, as well as on complex components such as gears, wheel bearings, and axles. The automated eight-frequency, multi-channel test set-up allows for simultaneous inspection for multiple anomalies on a single component.

The InSite CT works with Criterion NDT’s custom probes allowing for testing of complex geometries such as bearings, gears, axles, pistons, and tubing.
