Specifications
J2-2NM non-magnetic theodolite is a geomagnetic absolute observation instrument integrating opto-electromechanical technology, which can be used for multiple purposes, like both the geomagnetic declination angle D and the geomagnetic inclination angle I, and observing the total intensity F together with the proton magnetometer is an ideal combination of geomagnetic vector observation. The magnetometer can be used not only in geomagnetic stations, but also for mobile geomagnetic observations in the field. J2-2NM non-magnetic theodolite has the features of high observation accuracy, easy to carry, easy to operate, stable and reliable working performance.
