PQWT-GT300A Auto-analysis Geophysical Detector, 300m

PQWT-GT Auto-analysis Geophysical Detector is  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 instrument 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, so as to provide scientific basis for analyzing geological structures quickly and effectively.
