GC-CLY-2 Three-component Magnetometer (portable) is mainly used to measure the earth's magnetic field intensity (total field intensity B) and record the corresponding time, line number, point number and other values, as well as the daily variable data of the fixed earth's magnetic field intensity or the magnetic values of single points in different positions. Upon the change of daily variation of the magnetic field values of single points, they are used for the earth's magnetic field mapping and resource prospection inversion, etc.

Because of the absolute high measurement precision, large gradient tolerance and rapid response frequency, etc., the magnetometer is widely applied to the fields of geophysical ground magnetic prospecting, deep well geophysical magnetometry, and marine magnetometry, etc.

In addition, the product also can be used for basic network, underground magnetic anomaly source search, weak magnetic resonance signal acquisition of the seismic station, etc.; deep earth mineral resources detection and other marine engineering survey applications; efficient general geological and mineral survey, earth scientific research, geomagnetic survey, which are used to establish global geomagnetic field model.
