Pqwt S400 Multifunctional Underground Water Detector - China

price: 1.00 Dollar US$

PQWT-S400 is the use of natural earth field source without going through artificial field that is omitted clumsy

power supply system in order to achieve the simple, lightweight. After data collection, instrument through the unique

built-in computing functions to achieve the automatic presentation graph, the collected data can also be transferred to

a computer drawing to form a cross-sectional view, the geological layer structure can be quickly determined by a clear

understanding of cross-sectional view orebody ( seam ), hollow ( cave ), water ( aquifer ) specific information.


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 than 4 kg, 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.
