3-COMPONENT PRECISION MAGNETOMETER LEMI-044

Main features:

	High resolution and precision
	Temperature measurement channel
	32 GB SD memory card
	Low power consumption
	Relatively low cost
	3 years operational guarantee

An autonomous fluxgate magnetometer LEMI-044 is intended for 3-component measurements of Earth magnetic field in field conditions; it can be also used like reference base station. A special destination of this magnetometer is a record of magnetic field values under high voltage power lines to detect geomagnetically induced currents. It may also be used for magnetovariational research of underground structures, e.g. for mapping ore bodies. Three components of the measured Earth’s magnetic field data are stored in the SD card gridded to coordinates and time
