ELECTRICAL RESISTIVITY TOMOGRAPHY
GEMSOL UK Ltd is an expert in Magnetics method deployment and resistivity and Tomography Survey Electrical prospecting is one of the oldest methods of geophysical prospecting. Its implementation is relatively simple.
Direct current (in fact it is often crenels) is injected by means of two so-called injection electrodes and the difference in potential is measured by the result of two so-called measuring electrodes. This depends on the electrical resistance of the subsoil.
From where a wide range of missions:
