DC Multi Function Geophysical Resistivity IP Meter For Geophysical Studies
The two ends of the DC power supply are connected to the earth through the transmitting electrode, and a stable current field is established underground, and the distribution state of the current field is used to determine the occurrence state of rocks and ore bodies with different resistivities in the ground.
DC Geophysical Resistivity IP Meter an instrument for measuring the distribution shape of the electric field on the ground and then studying the distribution of formation resistivity.
