To solve the disadvantages of long measuring time and low efficiency of the traditional IP depth sounding method, Geomative has independently researched and developed the GD-20 multi-channel ERT electrical instrument, which adopts ERT components for the first time in the industry to conduct the multi-channel scanning test for high-power IP intermediate gradient scanning arrays.
Similar to the ERT resistivity method, users can arrange a set of AB electrodes and several sets of nonpolarizable electrodes, with the AB emission electrode connected to the AB terminal of GD-20 and nonpolarizable electrodes connected to taps of ERT cables. During the test, the instrument continuously emits, and multiple MN electrodes are simultaneously and automatically selected for testing multi-channel data. It can simultaneously conduct ERT IP test for data of up to 10 channels, which significantly improves efficiency and the density of mineral exploration projects.
During the high-power intermediate gradient scanning test, the AB high-voltage emission line is split from the ERT system, so that the emission voltage and current are not limited by the ERT system. The emission voltage can reach 1200V and the emission current can reach 6A, satisfactory to the high-power IP depth measurement.

The system is composed of the following modules:
GD-20 ERT IP system
Generator and high-power rectifier GP-5000
