WDZS-3 Multi-function Electrical Instrument for Groundwater Exploration/ Detection

                                            WDZS-3 Multi-function Electrical Instrument for Groundwater Exploration/ Detection

Application:

The method of electrical for groundwater exploration is the most economic, effective and widely used. WDSZ-2 is a special instrument for electrical prospecting water with the most parameters, the most function, and the most advanced performance at the present time. The instrument can be widely applied in ground water exploration, such as bedrock water, crevice water, lava water, and other application. It is also applied in metal and nonmetal mineral resources detection, city geophysical exploration, railway and bridge exploration, hydrologic geology and engineering geology such as searching for ground water, locate base of dam and flood protection levee incipient fault, can still used for geothermal prospecting.
