Surface Survey Geophysical Ip Resistivity Meter For Groundwater And Mining
WDJD-3 can be used for metal and nonmetal mineral resources detection, city geophysical exploration, railway and bridge inspection and so on; as well as in hydrology and engineering geology such as seeking for ground water, inspect dam base, flood protection levee for incipient faults, and geothermal prospecting.
Feature
1. High anti-interference performance and precision, integrated with multistage wave filtration and signal enhancement technologies.
2. In good condition, multi-electrode imaging function can complete measurement of a 552-data-points cross section.
3. Automatically achieving compensation of self-potential, drift and electrode polarization.
4. Receiving unit supports transient over-voltage protection, transmitting unit supports over-voltage protection, over-current protection and AB open-circuit protection.
5. Measured curve can be plotted through WDJD-3 mainframe.
