GIM Series DC Electrical System: A New Era in High-Density Electrical Resistivity Tomography

1. Technological Definitions & Evolution

The High-Density Electrical Method revolutionizes traditional DC electrical sounding through intelligent electrode arrays, enabling 2D/3D electrical resistivity imaging. At its core lies Electrical Resistivity Tomography (ERT), constructing geological models by detecting subsurface electrical property variations.

Compared to conventional systems, the GIM series integrates Multi-Channel Synchronous Acquisition with Segmented Centralized Distributed Wiring, supporting unlimited survey line extension. With 0.3%±1μV precision and 3200W transmission power, it achieves 1200V penetration capability.
