PQWT-JD3 Multi-function DC Resistivity Meter and IP Instrument for Underground Water Detector

PQWT-JD3 Multi-function DC Resistivity Meter and IP Instrument for

Underground Water Detector

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 (PQWT-JD3  multi-functional direct current instrument);

2.  DUK-2A type 60-channel or 120-channel multiplex electrode switch;

3.  Panel computer, Cables, electrodes and other related accessories.
