ADMT single-channel cavity detector series products use the earth’s natural electromagnetic field as the working field source to study the electrical structure of the earth’s interior. Based on the principle that electromagnetic waves of different frequencies have different skin depths in conductive media, the earth’s electromagnetic response sequence from high frequency to low frequency is measured on the surface to study the differences in electrical changes of geological bodies at different depths underground and determine the occurrence status of underground geological bodies.

ADMT series 3D imaging cavity detector is the most advanced 3D imaging professional geophysical archaeological detector in the industry. The instrument measures the strength of natural electromagnetic field to reflect the change of underground resistivity. It can analyze and judge the location, size, depth and other related information of underground cavities, earthworks, karst caves, etc. It plays a huge role in the construction of landfill leakage detection and cavity disasters. It is a geophysical professional cavity detector, which is favored by professional archaeological exploration enthusiasts and professional cultural relics and archaeological units.
