GEM - Model GSMP-20 - Supergrad Gradiometers Brochure

Increasingly, researchers are looking in to the applications of magnetics alone or in combination with seismic or radon measurements as means of monitoring geohazards (i.e. for earthquake prediction). It also has military applications. GEM’s solution for these types of installations is the Potassium SuperGrad. This special gradiometer is a system based on the Optically Pumped Potassium instrument – a unique technology that was developed in response to the United States Geological Survey’s need for an ultra-high sensitivity magnetic gradiometer.
