Electrical resistivity measuring instrument, Type DDC-8 uses apparent resistivity and can directly demonstrate the measured values, e.g. resistivity (Rs), average current (I) and average voltage (V). Electrical resistivity measuring instruments can be used in hydrology, environment protection, engineering geophysics and the exploration of metal and nonmetal mineral resources.
