DSHM-3 proton magnetic detector is a highly sensitive weak magnetism measurement meter, applying the theory of proton magnetic moment revolving freely in geomagnetism. It is applied to the observation of total geomagnetic field, including ground magnetic exploration of department like geology, oil, metallurgy and coal etc., surface base station of navigation and ocean magnetic measurement, magnetic variation observation of geomagnetic observatory in earthquake predict work.
Power consumption, reliable and stable in performance. High resolution, full automatic tuning, dot matrix graphic LCD, site measured curves display, data auto-record and storage, daily variation auto-calibration, can be connected with computer to process data, full English menu, simple operation, reasonable structure, small volume, light weight, strong anti-jamming ability.
