Resistivity Imaging System
A Resistivity Imaging System is a geophysical tool used to map the subsurface by measuring variations in electrical resistivity. It is widely used across many industries due to its ability to provide detailed information about underground structures, water content, and material composition. The GD-10 and GD-20 systems integrate electrical resistivity (RES), induced polarization (IP), and self-potential (SP) measurements into a single unit for comprehensive subsurface exploration. They support 1D, 2D, and 3D imaging using SP, IP, and RES data, making them versatile tools for detecting and mapping underground structures.
