LEMI - 004 magnetometer is produced on the base of fluxgate sensor all three components of which are implemented into one body, having rotating support with leveling facilities. Non-magnetic housing and minimal magnetism of components enable the instrument to be used conveniently close to the sensor. Special convenience provides step and smooth compensation of the initial field offset, what allows to realize maximal sensitivity at any measured field level.
