Scalar Magnetometers
GEM Advanced Magnetometers (GEM)
Many magnetic observatories today rely on a combination of scalar, fluxgate and theodolite instruments for obtaining measurements. Research installations engaged in volcanology applications are also using scalar magnetometers for stationary work. GEM?s Overhauser GSM-90 EUROMAG is particularly suited to these applications (and volcanology). This is a standard magnetometer without a display screen that can be operated via computer.
