Main Applications
This advanced geophysical instrument is designed to detect underground water and analyze subsurface structures using apparent resistivity and induced polarization methods. It is widely applied in mineral exploration, energy resource surveys, urban geophysics, infrastructure engineering, and environmental assessments. The device helps locate groundwater sources, resolve drinking water challenges for communities and industries, and identify potential risks in dam foundations, flood control systems, and mining areas. It also supports the detection of geological faults, collapse columns, landslides, and coal mine goafs. With optional 60-channel or 120-channel electrode switches, it can be integrated into multi-electrode resistivity survey systems.
