IDEA-ET/RFT intelligent all-digital multi-frequency, remote field eddy current detector 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, remote field 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. IDEA-ET/RFT has a complete set of eddy current testing system. integrated with the conventional multi-frequency, multi-channel, far-field eddy current testing systems, it can also turns to be high-performance, multi-purpose, intelligent eddy current testing apparatus.

instrument can also be switched to be two dual-frequency eddy curent testing detectors with two simultaneous probe connections.The testing frequency is 50Hz to 10MHz with a variable frequency range for choices (far field: 1HZ-10KHZ), 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 innder/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.
