Scalar Magnetometers for Observation

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 ...
