Switching box for the management of each group of 16 electrodes for electrical resistivity imaging (ERT); multiple MPX units can be serialized along the line. Controlled by POLARES or by RM1 acquisition software, the MPX units allow switching between current and potential electrodes in a fast and precise manner, at the same time providing extreme modularity to the system. Thanks to this solution, POLARES can expand as a number of electrodes, simply by adding accessories (i.e. 1 or more sets consisting of 16 stakes, 1 multi-electrode cable, 1 MPX extension) up to a maximum of 256 electrodes, without the need to modify the central acquisition unit. RM1 can manage a max. of 2xMPX for a total of 32 electrodes.
