Product Description

Geographic Surveying Instrument,Resistivity Imaging, Geo Tomography,  Electric Resistivity Tomograph,Ground Water Detector, Underground Water Detection for Sale
                                                                                       


Main Applications
This Geographic Surveying Instrument can be used in energy exploration and civil geophysical prospecting, railway and bridge survey, mental and non-mental mineral survey. It can also be used in hydro- and engineering geology survey, such as underground water, water reservoir dam site, flood control dam hidden trouble detection, and geothermic field survey.

Resistivity imaging, also known as electrical resistivity tomography (ERT) is a particularly useful survey method in clayey ground, where techniques such as Ground Penetrating Radar (GPR) are less effective. The method can also help to identify transitional boundaries in subsurface layers that can be difficult to detect using other geophysical methods and is a useful tool for locating deep seated sinkholes and mine workings
