We are professional manufacturer of geophysical survey and geophysical prospecting, such as geophysical instrument, resistivity meter, resistivity IP and SP system, resistivity, IP, SP, TEM survey, magnetometer, seismograph, gravity meter, proton magnetometer, drill, and element analyzer.
Application
It is applying parameters concerned with resistivity and stimulation polarization. It is widely used for searching metal ore such as lead zinc ore,gold ore,cooper ore,nickel ore,chrome ore,molybdenum ore,rare earth ore,zinc ore,lead ore,iron ore,tin ore etc.
It is also used for searching non-metallic mineral resources, underwater prospecting,city-geophysical prospecting,railways and bridges prospecting.
And it is used for geothermal prospecting,high resolution electronical prospecting, geological structure graphing etc.
