| | VLF ( very low radio frequency) electromagnetic receiver
This instrument, taking the magnetic wave of a very-low frequency radio station as the magnetic field source, measure the influences that the geology body affects the magnetic field parameters.
DDS-3 V.L.F ( very low radio frequency) electromagnetic receiver is only applied to explore the minerals and caves in the subsurface and fast gets the resistivity mapping; it has a good effect to explore the underground tubes, substructures and leaking dams.
Features
The instrument has a little reduction of magnetic wave and its field intensity is stable, low voices and a long time running. It supplies an ample intensity that it can be used in all the country land in china.
The measuring parameters: magnetic field horizontal and vertical components, polarizability ellipse inclination and the ground electric field horizontal component.
Easy to operation, stability and reliability, multi-use of one machine, and flexible usage.
Small volume, light weig
