Resistivity is defined as the amount of resistance to current flow, therefore the device can determine different soil compositions based on the readings. Such as if has underground water or cavity, the resisitivity vaule will be go down, the surveyor can analysis and location of groundwater.Widely application about geoelectrical resistivity meter geophysical instrument1.Rock soil conductivity layered,2.Groundwater detection,3.Bedrock burial survey,5.
