China Pqwt-S500 Water Flow 500m Underwater Detector Automatic Mapping Water Detector

PQWT-S500 geophysical prospecting mapping with one button underground water detector utilize the natural electric field as working electromagnetic field source, based on the resistivity differences of underground rock , ore or groundwater, measure natural electric field on the ground of N different frequencies electric field component.
PQWT-S500 natural electric field a key to mapping geophysical prospecting underground water detector is our latest research and development of products, using a number of patented technologies. The instrument weight is very light to carry easily , the measuring line need only 10 meters, one person will be able to complete the operation.
Main Features
1. High Speed and High Efficiency
Complete the acquisition of a measuring point using less than 30 seconds.
2. Easy to Carry
The weight of whole set is not more than10kg, easy to carry.
3. Simple Operation
Fully automated, high-speed CPU conducting voltage compensation automatically,
automatic gain adjustment, automatic filtering and signal enhancement, automatic
data processing and storage. Manage the instrument operation in 10 minutes, for
personnel withour any experience can be completed trainning within 2 hours.
4. Good Accuracy, High Accuracy
Resolution is up to 0.001mV, the accuracy rate is more than 95% in a large
number of field testing.
5. Anti-interference Ability
Strengthening the use of technology to suppress signal interference, highlight the
desired signal, the duplex frequency notch filter, multiple anti-jamming design,
digital filtering, combined with the traditional multi-filter filters, even in cities, or
other external electrical interferential workspace, but also be a good consistency
observed abnormal curve.
6. Flexible Electrode Layout
The instrument uses coarse, fine easy measuring electrode coarse and fine of two
studies, which saves a lot of time, they can get high-precision data. You can use the
bipolar profile, sounding poles, circular cross-section, multi-frequency sounding,
multi-frequency cross-section measurements and other cloth extremely efficient
exploration of different geological objects and solve different geological problems,
convenience of explanation. The maximum benefit analysis trends, depth and
thickness of groundwater.
