Pqwt S900 Multifunctional Geophysical Prospecting Instrument - China

PQWT-S900 Multifunctional Geophysical Prospecting Instrument Main Usage:

Geothermal resources, groundwater resource exploration;

Exploration of deep metallic and nonmetallic mineral resources in the earth;

Oil and gas exploration;

Mined out area of coal mine, karst development area exploration;

Highway, railway subgrade, tunnel and civil air defence works exploration.

Working Principle:

Geophysical exploration by studying and observing the changes of various geophysical fields to detect the geological conditions such as stratigraphic lithology and geological structure.

Geophysical prospectingmethods commonly used include gravity exploration, direct current exploration, alternating current exploration, magnetic prospecting, acoustic exploration, seismic exploration, radioactive exploration and so on, at present, the geological prospecting instruments on the market are mainly electrical prospectin, and most of the instruments have the characteristics of complicated operation, heavy equipment and complicated data processing, need for professional training of technical personnel to use, and requires years of experience.

PQWT-S900 Multifunctional geophysical prospecting instrument is the latest research and development of our products, adopt a number of patented technologies.

Instrument light weight and easy to carry, measured line only need 5-10 meters, single person will be able to complete the operation, saving manpower, full touch interfac, simple operation, External large capacity memory card, instrument with real-time drawing function, to search for high resistance(fault zone), low resistance(Such as water, ore belt census)real time drawing can react directly to the scene.

Innovative Design:

Compared with the traditional instrument, the key circuit is designed with discrete components, circuit

modular design, application of multiple shielding technology, reduce the noise of the circuit itself, achievegreater gain and resolution, Using higher precision of high speed AD, 8 channel sampling, precision switched capacitor filter, new system (column) high speed CPU, multi stage filter, two stage power frequencynotch, use signal enhancement technology suppression jamming, highlight useful signal.

The instrument adopts the whole aluminum shell, maximum suppression of electromagnetic interference, the utility model is suitable for geological exploration in various environments.

New power supply voltage and current detection, improvement of electrode line detection, program design using the latest digital filtering technology, Including FFT digital filtering, FIR, IIR and other digital filtering technology.

The combination of digital filtering and traditional filtering, frequency resolution up to 0.001Hz.

Support software online upgrade, all-new UI, optimization of human computer interface, make the instrument more simple and easy to use.

Major function：

Natural electric field frequency selection method;

Controlled source audio frequency magnetotelluric method(CSAMT);

Audio ground electromagnetic method(AMT) Main Features:

1 - Fast speed, high efficiency: The fastest can be less than 30 seconds to complete the acquisition of a measurement point.

2 - Easy to carry: The whole set of not more than 4 kg of weight, easy to carry and use.

3 - Simple operation: Full automation, Internal high speed CPU automatic voltage compensation, automatic gain control, automatic filtering and signal enhancement, automatic data processing and storage.

10min to learn how to operate the instrument, For those who do not have the experience of exploration can be completed within 2 hours of training.

4 - Good accuracy, high accuracy: Resolution up to 0.001 mV, In a large number of field tests, the accuracy rate is over 95%.

5 - Strong anti-interference ability: Signal enhancement technique to suppress interference, highlight useful signal, dual frequency notch filter, multiple anti interference Design, the combination of digital filtering and traditional filtering multiple filter, Even in the city, strong interference or other external interference zone, good agreement can be observed in the abnormal curve;

6 - Pole flexible, traditional and unique pattern: Instruments used for rough, fine measurement two kinds of electrodes convenient rough and fine study, that saves a lot of time, and high precision data can also be obtained.

can use polar profile, polar sounding, circular section, Multi frequency sounding, Multi frequency section a variety of methods for measuring cloth poles, efficient exploration of different geological objects and Solution of geological problems of different tactics, easy explanation maximum benefit analysis of groundwater movement, depth and thickness.
