Overview
High-Precision Geomagnetic Measurement
The DSHM-3 proton magnetic detector is a highly sensitive instrument designed for measuring weak magnetic fields based on the principle of proton magnetic moment precession. It is an essential tool for total geomagnetic field observation, supporting applications in geological exploration, oil and gas surveying, metallurgy, and coal mining. Additionally, it is suitable for surface base station navigation, ocean magnetic measurement, and geomagnetic observatory monitoring for earthquake prediction.
