DJF high power DC electrical measuring system consists of a DZ-2 rectification power supply (5-15kw optional), a DJF-2 DC electrical transmitter (5-15kw optional), one or multiple DJS-9 DC electrical receivers or DJR-2 waveform electrical receivers, AB power lines/ electrodes, data processing software and related accessories. DJF high power DC electrical measuring systems are widely used for mass screening and detailed detection of metal and nonmetal mineral resource survey, high-precision mineral resource survey and the exploration of underground water resources.

Feature
  • There are multiple synchronization mechanisms to ensure accurate and prompt measurement, including GPS, pulse delay and high accuracy quartz clock, guaranteeing repeatability and consistency.
  • The high transmitting power (5kw, 10kw and 15kw optional) can meet various detection requirements.
  • Transmitter and receiver can both record travel time automatically. The system can record the power supply current and receive a field electric potential value at a set timing, so as to calculate the apparent resistivity accurately.
