DDC-8 Geological Equipment Ground Resistivity Meter Ground Water Finder, Underground Water Detection, Ground Water Detector, Water Finder, Ves Vertical Electrical Sounding, Geoelectric Groundwater Finder

DDC-8 resistivity meter features and applications:
1. With the variation of apparent resistivity, it is widely used for searching underground water and non-metal ores (quartz mine, calcite mine, coal ore and talc ore etc), which also plays an important role in sides as ores prospecting and water detect etc.
2. Micro-PC controlled, resistivity value read directly, multiple arrays, data protection when power-down.
3. It is applied for ground and sap's electrical prospecting method like vertical electrical sounding (VES), electro-profile method, IP charge method and SP method etc. The applied field includes hydrology, environment, engineering prospecting, metal and non-metal mineral source detect etc.
