WDDS-2 Digital Earth Electrical Resistivity Meter

WDDS-2 Digital Earth Electrical Resistivity Meter is a new generation underground water detector, with function not only support SP survey but also VES sounding.
  • WDDS-2 Resistivity meter


Widely Application:

1.Geothermal prospecting with vertical electric sounding resistivity 

2.Metal and nonmetal mineral resources detection 

3.City geophysical exploration, railway and bridge inspection and so on

4.Hydrology and engineering geology as seeking for ground water, inspecting dam base and flood protection levee for incipient faults

Features for WDDS-2 Resistivity Meter

In 1D Vertical Electrical Sounding survey, WDDS-2 resistivity meter power can up to 3500W of power supply,can be emitted to allow excited pulse signals to reach deeper strata.  Prior to field testing, measurement array configurations and the electrode scanning parameters can be in putted into the monitoring host, thus reducing the time spent in field to enter the survey parameters and increase survey productivity.

1D software effect


With built-in 12V lithum battery( also support external 12v battery), that's can support  20 hours continously work at field when detecting underground water

Water finder
