Electrical Resistivity Meter Underground Water Finder Geophysical Survey Equipment Groundwater Exploration Ves Survey DC Resistivity Meter For Water Detection
Electrical Resistivity method is one geophysics method which is used in the investigation of groundwater.Some recent studies about detection ground water using Vertical Electrical Sounding (VES) method. The VES is a geoelectrical method for measuring vertical change of electrical resistivity. The VES gives detail information on the vertical succession of different conducting zones or formations andtheir individual thickness and true resistivity below a given point on the earth surface.The principle of VES method is injected electric current into the earth through two electrode currents. Thepotential difference that occurs is measured through two electrodes potential. The results of measurementof current and potential difference for each particular electrode spacing, can be determined variations ofresistivity value below the measuring point (the point of sounding).
1 By utilizing the apparent resistivity parameters, it is widely used in hydrology, environmental protection, engineering geophysical exploration, metal and non-metal mineral resources exploration.
2 Microcomputer controlled, direct-reading resistivity, various electrode arranging mode, data protection against power-failure

The theoretical basis of electric water search is scientific, because the resistivity reflects the electrical conductivity of the underground rock, so the resistivity value we get just reflects the electrical property of the rock, so the water level we find is accurate. After the water level is found, the depth of the water level can be obtained by applying the sounding method on the water level. At the same time, the trend and inclination of the water-bearing structure can be obtained according to multiple sounding points. method incomparable.
