ELECTRICAL IMAGING SYSTEM IN ALTERNATE CURRENT POLARES 2.0 GEOPHYSICS www.pasigeophysics.com POLARES BOX TECHNIQUE: Electrical imaging applied to geophysical exploration has been using the same traditional method for acquiring data of the traditional VES soundings with 4 electrodes: an electric current was applied between two electrodes and the correspondent voltage was measured between other two electrodes inserted in the ground. Applied current and the related voltage were always continuous, with an inversion of polarity for each measurement. POLARES 2.0 uses a sinusoidal alternate current...

ELECTRICAL IMAGING SYSTEM IN ALTERNATE CURRENT POLARES 2.0 GEOPHYSICS www.pasigeophysics.com MAIN FEATURES: Compact, easy-to-use, the POLARES IMAGING SYSTEM can measures and display: ground resistance, current, voltage, self potential and standard deviations and IP. Computation of the apparent resistivity for the most used configurations of electrodes arrays: Schlumberger, Wenner, Dipole-Dipole (User defined configurations are also available trough Utility Software delivered with the instruments) With its automatic “multiplexer” to commute signals on the different electrodes, the istrument can...
