Main Characteristic:
1. By utilizing the apparent resistivity parameters, it is widely used in hydrology, environmental protection, engineering geophysical exploration, metal and non-metal mineral resources exploration.
2. Easily can observe the apparent resistivity and apparent polarizability at the same time.
3. Measurement and control host can work standalone and it has all the functions of DZD-6A multi-functional direct current instrument.
System components:
1. Measurement and control host (DZD-6A multi-functional direct current instrument);
2. DUK-2A type 60-channel or 120-channel multiplex electrode switch;
3. Cables, electrodes and other related accessories.
