One. Overview
The CZM-5 proton magnetometer is a low-intensity magnetic measuring device with high-sensitivity ,made under the principle of the free rotation of hydrogen proton magnetic moment in the geomagnetic field. This device is widely used for the observation of the absolute field strength of the earth's magnetic field, the ground magnetic prospecting of Department of geological, petrolic, metallurgical and coal, and magnetic variation observation of marine and aerial magnetic survey surface daily change station and earthquake forecasting geomagnetic station.
