PQWT-225C Water Detector（Original price: $1119，Current price: $729）

The PQ225 series Natural Electric Field Water Detector uses the magnetotelluric field as the field source, utilizes the difference in conductivity of different underground geological structures, and accurately measures the changing laws of electric field components of different frequencies to deeply study the geological structure and its changes, providing strong support for the scientific exploration of groundwater resources.
