This geophysical surveying instrument is widely applied in energy exploration, civil engineering, railway and bridge inspections, and mineral prospecting for both metallic and non-metallic resources. It is also utilized in hydrogeological and engineering surveys, including underground water detection, reservoir dam assessments, flood control dam inspections, and geothermal field investigations.
Electrical Resistivity Imaging (ERT) is highly effective in clay-rich terrains where methods like Ground Penetrating Radar (GPR) often fail. It excels at identifying subsurface layer transitions and detecting deep-seated anomalies such as sinkholes and abandoned mine workings.
The system employs advanced techniques like Vertical Electrical Sounding and Electrical Profiling, using configurations such as Wenner Array, Dipole-Dipole, and Schlumberger Array for precise subsurface mapping. Key features include a Multi-electrode Resistivity Imaging System, Non-polarized Electrodes, and a Multiplex Electrode Converter for enhanced data accuracy.
Applications extend to Hydrology, Geothermal Exploration, and Mineral Exploration, with capabilities like measuring Apparent Resistivity, Induced Polarization, and Ground Resistance. The instrument integrates a Transmitter and Receiver with Synchronization Mode, ensuring reliable data collection across multiple channels for comprehensive Geological and Geophysical Exploration.
