We are one of largest professional and reliable manufacturers of geophysical survey and geophysical prospecting, such as geophysical prospector, resistivity meter, VLF system, electrical prospecting, high density prospecting instrument, groundwater detector, mineral prospector, ore detector, gold detector,water locator,resistivity imaging survey, electromagnetic system equipment, electrical resistance, resistivity IP and SP system, resistivity, TEM survey, TEM system, EM system, magnetometer, radioactive detector, seismograph, gravity meter, logging system,proton magnetometer, drill equipment, drill rig, well drilling equipment, core drilling equipment, hydraulic drill equipment, and element analyzer.
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 20 years practices,we achieved a remarkable performance and have been the praise of the majority of our customers.
