Soil Resistivity Measurement Methods DC Resistivity Meter 4 Wire Resistance Meter
WDDS-2C digital resistivity meter is a new generation of DC resistivity equipment which is based on a series of advanced electrical equipment of BTSK for resistivitysurvey, and adopts 32-bit microcontroller technology and 24-bit A / D technology development. It applies for 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.

Tablet PC: Windows 10 64 bit operating system, memory no less than 2GB, storage capacity no less than 32GB, Bluetooth, USB.
WDDS-2C is equipped with 7.4V lithium battery with automatic
protection which can auto-power-off when battery voltage is lower
than 6.6V. When the voltage is lower than 6.8V, system prompts
“Battery voltage is too low”. Then the operator needs to charge the
mainframe to avoid cut off automatically. Or to wiring with an
external 12v battery by the standard battery line in our standard
configuration.
