Principle
NEF series full automatic self-potential frequency method is based on the natural electrical field method, magnetotelluric sounding method, frequency sounding method, AMT system, with the view of lightweight, efficient, accurate and simple, it judges and analyzers the geological abnormity we need to search by measuring relative parameters changes such as resistivity generated by different structure. And according to the relative physical parameter changes such as the different conductivity of the ore body and non-ore body, we can estimate underground abnormous geological conditions like location, direction, buried depth, shape and volume etc.. After nearly *0 years practices, we achieved a remarkable performance and have been the praise of the majority of our customers.

Application:
1.Widely used in metal ore prospecting, non-metal ore’s detailed and general survey to decrease the venture of mineral investment and improve exploration success rate and scientificalness.
2.Applied in underground water detecting to meet the demand of drinking water, industrial usage and agricultural irrigation.
3.Also used in engineering geological prospecting, disaster geological detect, coal goaf, archaeological mining, city exploration, non-metal pipe survey as well.
