High Accuracy Magnetometer
The CTM-DI(B) high accuracy magnetometer can precisely measure the geomagnetism declination angle (D) and geomagnetic inclination angle(I). The magnetometer can be used in geomagnetic observatories and in the wild. CTM-DI(B) magnetometer is currently the most accurate instrument on D, I measurement. With stable performance and broad application, the magnetometer is easy to operate and convenient to carry. The combination of CTM-DI(B) magnetometer and proton precession magnetometer would be an ideal tool for geomagnetic vector observation. The CTM-DI(B) magnetometer can be widely used for geomagnetic science research, data collection, national defense, earthquake prediction, exploration of oil and minerals and navigation for ships and airplanes etc. The magnetometer can practice measurement in a geomagnetic observatory or at a wild observation spot.
