LEMI - 204 magnetometer is intended for absolute magnetic measurements. It's produced on the base of one-component fluxgate sensor. The construction of its housing has the fixation side which fits the corresponding fixation place of the theodolite and allows adjusting conveniently the direction of magnetic axis of the sensor. The non-magnetic 3T2KP-NM theodolite is also available and can be procured together with the magnetometer. The digital interface allows to build automatized magnetic observatory with minimal operator work.
