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.

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.
