WDJD-4A RES & IP Multiple Electrodes Survey System
 

  WDJD-4A The WDJD-4A is a highly integrated RES & IP measurement system designed for 2D electrical resistivity tomograph and 1D induced polarization surveys in subsurface. Users can directly set measurement parameters and view measurement results on the WDJD-4A mainframe screen. Subsequent data can also be transferred to computers, tablets, and other mobile devices. The WDJD-4A delivers an impressive transmission power of 6600W@1100V, 6A, enabling current penetration through approximately 300 meters of underground rock formations with excellent resolution. 

  Additionally, the WDJD-4A features highly efficient measurement capabilities, typically requiring no more than 15 minutes to measure a cross-section comprising 552 points. Over 18 electrode arrangement options provide greater flexibility for users when configuring electrodes on-site. We have installed induced polarization measurement interfaces and modules on the mainframe to assist clients in acquiring more comprehensive subsurface rock formation data and exploring a wider variety of underground mineral deposits.

Main Features

* High Power:
Maximum transmit power of 6600W at 1100V and 6A ensures detection of rock layers up to 300 meters deep and acquisition of high-resolution apparent resistivity and apparent polarization data
* Flexible Layout:
Over 18 types of electrode configurations provide greater flexibility for field operations
* Accurate & Efficient:
Under conditions that ensure good repeatability, the time required to measure a cross-section comprising 552 points generally does not exceed 15 minutes
* Grounding Self-Test:
In field operations, you can conveniently and quickly check whether each electrode is properly grounded at any time
