Vertical Electrical Sounding Resistivity Meter Underground Water Detector with 2D Result Geophysical Equipment
WDDS-2/2B digital resistivity meter (hereafter also referred to as WDDS-2/2B mainframe or WDDS-2/2B meter) is a new generation of DC resistivity equipment which is based on a series of advanced electrical equipment of resistivity survey, and adopts 32-bit microcontroller technology and 24-bit A / D technology development.
>>Applications of the Resistivity Meter Underground Water Detector:
* Metal and nonmetal mineral resources detection
* City geophysical exploration, railway and bridge inspection and so on
* Hydrology and engineering geology as seeking for ground water, inspecting dam base and flood protection levee for incipient faults
* Geothermal prospecting
