CZM-2A proton magnetometerDetailed product description：

The CZM-2A proton magnetometer is made based on the principle of free rotation of hydrogen proton magnetic moment in the geomagnetic field, and is a high-precision magnetometer capable of measuring the absolute value of the total geomagnetic field.
The CZM-2A proton magnetometer is mainly used for ground magnetic exploration and can be used for the general survey, detailed investigation, and geological mapping of iron and other metal deposits; Ground daily variation station observations for aeromagnetic and oceanic magnetic surveys, magnetic variation observations for geomagnetic stations in earthquake prediction work, and mobile magnetic surveys; In addition, it can also be used for the detection of small ferromagnetic materials. This instrument is particularly suitable for working in weak magnetic fields.

Main Features
