DWJ-3B IP & Resistivity Receiver
DWJ-3B is a new generation DC-mode receiver that can be used in the
measurement of 
Resistivity method and Induced polarization method, and can also
display the Apparent Resistance Rate & Apparent Stimulation
Rate, Half Decay time, Cumulative Sum, Degree of deviation,
spontaneous potential, supply current and primary field ,etc.
Search for Groundwater sources, Hydrological engineering, and Geological exploration, etc.
