598 portable eddy current detector is placed on the detected material with electromagnetic base probe ,there is a excitation coil on probe，as well as one or two detecting coil，detection has some advantages such as ：detected material’s surface doesn’t have to be cleaned;probe doesn’t touch the surface of material，the change of interval between probe external diameter and material inner diameter has less effect on detecting result。The sensitivity of external surface and internal surface of detecting material is same;it has high degree of sensitivity on uniform reduction and gradually reduce ，the detecting speed of probe is even or not which has no effect on detecting results ;the gas and liquid medium have no effect on detecting result 。Detecting equipment is small size，light weight so as to be took advantage at the scene conveniently .

598 portable eddy current detector is a new generation eddy current nondestructive detecting equipment ，it adopts the latest DSP and FPGA digital electronic technology 、far field eddy current technology and microprocessor technology so it can real time and effectively detect flaw of metal parts ，it doesn't affected by probe lift-off 、skin effect、conductivity and uneven magnetic permeability.

598 portable eddy current detector is not only a whole far field eddy current detecting system,but also with properties of multiple frequency 、 eddy current detector ,especially having high sampling rate and high signal -to noise ratio，make it becomes to be high-performance 、multiple application 、intelligent new type of eddy current detecting equipment in Asian-pacific region。

598 portable eddy current detector is used for detecting every kind of metal parts , detecting equipment including signal power source、signal measurement 、signal recording and dealing，producing the form which can pass through the tube。
