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.
Main application:
Making using of the relative parameters of apparent resistivity method and IP survey, it is widely used for searching metal ores (lead zinc ore, gold ore, manganese ore, copper ore, nickel ore, chrome ore, molybdenum ore, rare-earth ore, zinc ore, lead ore, iron ore, tin ore etc), non-metal ores, energy source and underground water etc, also for city prospecting, railway & bridge engineering exploration, geothermal investigation, high density resistivity survey and geological structural mapping etc as well.
Principe:
It can get the profile graphs by means of the related parameters such as the apparent resistivity and induced polarization, then can analyze the abnormality position. The maximum prospecting depth can reach 1000m.
