PQWT-GT Auto-analysis Geophysical Detector is the eighth generation of multi-channel prospecting instrument newly developed by Hunan Puqi Geologic Exploration Equipment Institute and Hunan Puqi Water Environment Institute Co. Ltd.
It is based on the principle of natural electric field frequency selection method. It is widely used in underground water sources, geological structures, mine veins, mine tunnels, cavities, karst caves, ant holes, mined-out areas, dam pipe surge, landslides and other fields.
This series of instruments integrates 5 independent invention patents of PQWT, including data acquisition system, data processing system, automatic mapping system, automatic analysis system and circuit system.
It realizes the simultaneous data acquisition of multi-channel and multi-frequency, completely solves the influence of unstable factors caused by the time difference of the natural electric field source, and greatly improves the accuracy and work efficiency.
The instrument can process the collected data, automatically draw curve map, profile map, and 3D renderings in real time, and automatically analyze abnormal areas, to provide scientific basis for analyzing geological structures quickly and effectively.
