Measurement range of EEC-39RFT four frequency far-field eddy current tester

The EEC-39RFT four frequency far-field eddy current testing instrument is a new generation of eddy current non-destructive testing equipment. It adopts advanced DSP and FPGA digital electronic technology, far-field eddy current technology, and microprocessor technology, which can effectively detect the inner and outer wall defects of ferromagnetic metal pipelines in real time during far-field detection without being affected by probe lifting, skin effect, uneven conductivity and magnetic permeability. EEC-39RFT is not only a complete set of remote field eddy current testing system, but also has the advanced performance of conventional multi frequency and dual channel eddy current testing instruments, especially with high sampling rate, ultra-low noise and high signal to noise ratio, making it a high-performance, multi-purpose and intelligent new eddy current testing equipment in the Asia Pacific region.
