HEF-24ET Digital Multi-channel Eddy Current Flaw Detector for Inner/Outer Wall Cracks

HEF-24ET Intelligent Digital Multi-channel Real Time Eddy Current Inner Wall and Outside Wall Cracks Flaw Detection

Particularly applicable to nuclear energy, electric power, petrochemical, aerospace, aviation and other departments in the service of copper, titanium, aluminum, zirconium and other pipes, metal parts of the flaw detection and wall thickness measurements, and a variety of ferromagnetic pipeline testing, analysis and evaluation.

HEF-24ET intelligent all-digital multi-frequency eddy current testing instrument is a new generation of eddy current non-destructive testing device, With the adoption of the most advanced digital electronic technology, multi-frequency eddy current technology, and microprocessor technology, it can achieve effective inner wall and outside wall cracks detection of the ferromagnetic and non- ferromagnetic metal pipes in real time.

HEF-24ET has a complete set of eddy current testing system. integrated with the conventional multi-frequency, multi-channel, conventional eddy current testing systems, it can also turn to be high-performance, multi-purpose, intelligent eddy current testing apparatus.

With four relatively independent testing channels, HEF-24ET can receive four absolute and four differential eddy current signals. via the soft switching, the instrument can also be switched to be two dual-frequency eddy current testing detectors with two simultaneous probe connections. The testing frequency is 50Hz to 10MHz with a variable frequency range for choices, and it has the function of weak testing signals amplification and strong anti-jamming capability. Applied to the tube cracks testing, with inner-through probe, it can easily detect the defects such as inner/outside wall surface crack, pits, corrosion, thinning, wall materials and internal defects. And it has the feature of computer-controlled auto-testing, digital display, high testing sensitivity, stable performance and so on.

Therefore, HEF-24ET particularly suitable for various in-service metal (copper, titanium, aluminum, zirconium and other metal material) tubes and metal parts flaw detection and wall thickness measurements and evaluation analysis in nuclear energy, electric power, petrochemical, aerospace, aviation and other departments. More detailed, such as the testing of before service or in service boiler tube, heat exchanger tubes, underground pipes and cast iron pipes etc.
