The PQWT-GT Series is the 8th-generation of multi-channel prospecting instrument newly developed by PQWT 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.
PQWT GT series of instruments integrates 5 independent invention patents of PQWT, including data acquisition system, data processing system, automatic mapping system, auxiliary 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.
Product Features Auxiliary Analysis: The instrument analyzes the abnormal area with one click. Automatic Mapping: Automatically draw curve map, profile map, and 3D renderings. Stable and Reliable: Collect 18 points data with one-time wiring. Supplementary Measurement Function: The extension of geological structure can be analyzed by making supplementary measurement in front and rear of the survey line. Data Storage: It can store curve map, profile map, and 3D renderings of more than 999 survey lines to facilitate the production of geophysical exploration reports.



Product Components
① Host machine: Collect and process data.
② Tool bag: Store tools.
③ Electrode rod: Connect the cable and the ground to be tested.
④ Battery: To supply power to the host.
⑤ Cable: Connect the host.
⑥ Charging stand: Charge the battery.

The PQWT-GT500A can detect underground water sources and geological structures at depths of up to 500 meters.
The PQWT-GT500A uses the natural electric field frequency selection method, which is effective for multi-channel prospecting.
It is widely used in detecting underground water sources, geological structures, mine veins, mine tunnels, cavities, karst caves, and more.
The instrument automatically draws curve maps, profile maps, and 3D renderings based on the collected data in real time.
Yes, it has an auxiliary analysis feature that allows users to analyze abnormal areas with a single click.
The PQWT-GT500A can store curve maps, profile maps, and 3D renderings of more than 999 survey lines.
The package includes the host machine, a tool bag, electrode rods, a battery, a cable, and a charging stand.
Yes, the instrument is designed for ease of use, with automatic features that facilitate operation for both beginners and professionals.
The supplementary measurement function allows users to analyze the extension of geological structures by taking additional measurements in front and rear of the survey line.
The PQWT-GT500A is powered by a rechargeable battery that provides the necessary power for the host machine.
Please refer to the manufacturer's warranty policy for specific details on the warranty period for the PQWT-GT500A.
The data processing system enables simultaneous data acquisition from multiple channels and frequencies, improving accuracy and work efficiency.
While the PQWT-GT500A is designed to be durable, it is recommended to avoid extreme weather conditions to ensure optimal performance.
The manufacturer typically offers training sessions and resources to help users understand how to effectively operate the PQWT-GT500A.
Charging time may vary, but it usually takes a few hours to fully charge the battery depending on the specific charger used.
