CZM-2A proton magnetic detector is made based on the theory of proton magnetic moment revolving freely in geomagnetism, which is a magnetic detector that can measure the absolute value of total geomagnetic field.
CZM-2A proton magnetic detector is mainly used in ground magnetic survey, such as the general and detailed survey of iron ore and other metal ore deposit, geological mapping; surface daily variation base station observation of navigation and ocean magnetic detect, magnetic variation and flow magnetic observation of geomagnetic observatory in earthquake predict work; also small ferromagnet detect etc. as well. It is especially suitable for weak magnetic field work.

CZM-2A proton magnetic detector features:
It has many advantages such as small volume, light weight, digital display, high precision, wide measuring range, strong anti-jamming ability, small power consumption, convenient operation and read, firm structure, reliable and stable in performance etc.CZM-2A proton magnetic detector is consisted by mainframe and probe.
