DX-370 Fluxgate Magnetometer

DX-370 Fluxgate Magnetometer

DX-370 fluxgate magnetometers is a kind of instrument which can accurately measure the weak static and dynamic and low frequency vector magnetic field. The fluxgate meter has the characteristics of high stability, high linearity and accuracy, full digitalization, etc. It adopts the world's top fluxgate probe. Compared with the magnetic field measuring instrument based on the principle of hall effect or magnetoresistance effect, it is the best choice to measure the weak magnetic field. It has digital and analog signal output, and the unique can bus network interface is suitable for multi array magnetic field testing, which is widely used in science and technology research, military, aerospace and other departments.
