PQWT-KD 50M underground cavity cave detector manufacturer resistivity

PQWT-KD Series geophysical prospecting instrument: the use of natural electric field source as a working farm, with resistivity contrasts underground rocks and minerals or groundwater, based on measuring the natural electric field on the surface of the N different frequency electric field component, according to their different variation to study Abnormal changes in geological bodies produce, reaching solve geological problems one electrical prospecting methods.Because this method measures the electrical component of the electromagnetic field of the earth, so called natural electric field method; and we chose the corresponding frequency as measured within -50 meters, that were selected frequency, so called frequency selection method, it is always referred to as natural potential frequency method.


Advantage:

1:High Measurement Speed and high efficiency

2.Convenient to Carry

3:Simple operation

4:Good performance and high Accuracy

5:Strong Anti-interference Ability

6:The unique feature of Automatic mapping
