The PQWT-TC300 Full Automatic Mapping Underground Water Detector is a professional geophysical instrument designed for efficient underground water detection up to 300 meters depth. Utilizing natural electric field frequency selection technology, this advanced system provides accurate mapping capabilities for geological surveys and water resource exploration.

This instrument operates on the principle of electrical differences in the natural earth magnetic field. By analyzing electromagnetic field changes across multiple frequencies, it detects underground material variations to solve geological problems. The measurement data is captured as self-potential with millivolt units.
