Georesistivimeter fot Time Lapse Analisys for measuring the alteration over time of the soil’s resistivity profile.
G.Re.T.A. is the most effective and innovative solution for Permanent Geoelectric Monitoring of the conditions of large sections of soil. This instrument measures the alteration over time of the soil’s resistivity profile, functional to the characterization of the same in terms of water content, presence of cavities or other anomalies.
Multielectrode Electric Tomography (ERT) is based on the insertion of an electric field in the ground through electrodes (input electrodes), and the measurement of the voltage is effectuated through other electrodes (measurement electrodes). From the measure of the voltage it is possible to obtain, through the second law of Ohm, the resistivity value, a peculiar characteristic of all materials.
