PQWT-KD50.50M Cavity Detector

PQWT-KD series automatic mapping cave detector is based on the earth's electromagnetic field as the field source, based on the difference in the conductivity of different underground geological structures, and by studying the variation law of the electric field components at different frequencies to study the geological structure and changes, to search the underground geological areas such as underground mined area, caves, loose soil, tunnels, and ants, and has a very good detection effect on engineering geology, archeology, and disasters.
