Electrical Resistivity Survey Meter Geophysical VES Test Equipment for Groundwater Surveying
WDDS-2 Resistivity Meter is the basic resistivity meter only with function of 1D Res Sounding
This resistivity meter is the new generation DC resistivity instrument using 32-bit single chip computer technology and 24-bit A/D technology. Widely used in metal and non-metal resources exploration, civil geophysical prospecting, railway and bridge prospecting etc, it also can be used in hydrology and engineering geology prospecting such as underground water exploration, dam foundation setting out and dam hidden danger exploration etc. This instrument can be applied to geothermal prospecting.
