Products Description
The WDDS-2 Geo Resistivity Meter is a professional geophysical instrument designed for mineral exploration, engineering geological investigation, and deep underground structure detection.
Using high-power DC resistivity technology and advanced data acquisition systems, it provides reliable electrical data for analyzing underground formations, identifying abnormal geological zones, and building 2D resistivity profiles.
With up to 3500W transmitting power, 1000V output voltage, and professional inversion software compatibility, the WDDS-2 is widely used by geological institutes, mining companies, and infrastructure survey teams for mineral prospecting, tunnel investigation, and engineering site evaluation.
Why WDDS-2 Geo Resistivity Meter for Professional Geophysical Surveys?
Higher Power for Deep Exploration
Deep geological targets and high-resistance formations require strong transmission capability. WDDS-2 Geo Resistivity Meter delivers up to 3500W transmitting power and 1000V output voltage for deeper resistivity surveys.
