PQWT-G150.150M Dam Piping Leak Detector 

PQWT-G150 Dam piping leak detector is based on the earth’s electromagnetic field as the field source, based on the difference in the conductivity of different underground dam geological structures, and by studying the variation law of the electric field components at different frequency to study thegeological structure and changes, to find dam leaking by scientific method. It can find geologic structure such as piping leaking points, ants cavern, bedrock foundation leaking points, loose soil, and ants, and have a very good detection effect on dams and other engineering disasters.


1. The instrument can automatic mapping and get result on site.
