XIYI-24ET digital multi-frequency eddy current detector has four relatively independent test channels, which can obtain two absolute and two differential eddy current signals at the same time. The instrument can be switched to two single-frequency eddy current detectors by a soft switch, with two probes connected at the same time. With a variable frequency range of 50Hz to 10MHz, the instrument has extremely high amplification and strong anti-interference ability for weak signals of eddy current detection. In the pipeline detection using the internal through the probe, once through the pipeline can be measured in the wall, the surface of the cracks, pits, corrosion, thinning and the internal defects of the wall material, and its automatic detection by computer control, digital display, high sensitivity, stable performance and other advantages.
