Agricultural Water Investigation by Resistivity Imaging & IP Method

Detection Equipment For Underground Water And Ground Water  

Main Applications

By utilizing relevant parameters of apparent resistivity and induced polarization method, the instrument is widely used in many aspects including metal and non-metal mineral resources exploration, energy exploration, city geophysical exploration, railway and bridge engineering exploration, etc.

Search for groundwater, solve the human and animal drinking water issue as well as industrial and agricultural water issue. Determine the hidden safety risk location in reservoir dam foundation and flood-control dyke, find faultage zone and collapse column, landslides, coal mining goaf, search for geothermal and other hydrological, engineering geological exploration.

Accessories made by our factory with 60-channel or 120-channel multiplex electrode switch, also can be used for multi-electrode resistivity survey system.
