Function
The WGMD-9 super high-density electric system represents a cutting-edge advancement in electronic technology. Developed utilizing state-of-the-art components like the Chinese Pocket PC, Bluetooth, 24-bit A/D conversion, and high-power control, it stands as a new generation system. Notably, this high-density electrical system achieves remarkable reductions in instrument volume and weight, surpassing current domestic and international standards. Its exceptional technical indicators and functions position it ahead of existing instruments in the industry. Moreover, its enhanced capabilities enable superior performance even in challenging and complex field environments.
The entire system is controlled by the WDA-1 super digital DC electric instrument, which can perform centralized multi-electrode survey cable and electrodes, as well as distributed 2D/ 3D multi-electrode resistivity survey and 2D multi-electrode Res & IP survey with distributed multi-electrode survey cable and electrodes.
