CZM-4 proton magnetometerDetailed product description：

The CZM-4 proton magnetometer is a high-sensitivity weak magnetic measurement device developed based on the principle of free rotation of hydrogen proton magnetic moment in the geomagnetic field. Its magnetic field measurement accuracy is ± 1nT and the resolution is as high as 0.1nT, fully meeting the requirements of the "Ground High Precision Magnetic Measurement Work Regulations" issued by the local mining department. Its unique large storage capacity, high resolution, and flexibility can be widely used as portable, mobile, and base station magnetometers.

Main Features

The absolute measurement range of the total field of the geomagnetic field is 20000nT to 100000nT, which can be used in any region of the world; It can be automatically tuned across the entire range or manually tuned; Automatic measurement of geomagnetic field values is particularly convenient for users who are unsure of the normal local geomagnetic field values. Chinese operation interface, automatic data recording and storage, and real-time display of magnetic profile curves, easy to operate; Randomly equipped specialized software can perform relevant preprocessing on field measured data, such as smoothing denoising, daily variation correction, and drawing profile curves, making it convenient for users to evaluate the indoor work effect of the day; USB 2.0 communication interface enables faster data transmission from instruments to computers; Can be used for parameter determination of magnetic specimens; Optional 1GB or 2GB data storage and a set of backup batteries are available to meet the long-term magnetic measurement requirements; Can be connected to an external GPS receiver upon user request to store the coordinate values of measurement points; Professional magnetic data processing software can be selected for users to draw contour maps, plane profiles, and perform forward and inverse interpretation.
