NEF series full automatic geophysical prospector(NEF**0/NEF**0)

 

Description:

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.
