Advanced Magnetometers & Gradiometers

Advanced Magnetometers & Gradiometers

GEM Advanced Magnetometers is a supplier of magnetometers, gradiometers and magnetic sensors for Earth Science, Geophysics and other applications. With more than two decades in the research and development of equipment for geophysical exploration, GEM is also known for its service and support – featuring knowledgeable magnetics professionals and the industry-leading two-year warranty program.

Advanced Quantum Magnetometer Technologies

Quantum magnetometers take advantage of the spin of subatomic particles (nuclei and unpaired valence electrons). Through a process of polarization, particles are caused to precess in the earth's ambient magnetic field. The resulting frequency of precession can be translated directly into magnetic field units. Quantum results are scalar (total field intensity) as opposed to vector (i.e. from fluxgate geophysical instruments or GEM's Suspended dIdD technology).

GEM leads in developing advanced quantum magnetometer technologies, including the Overhauser, optically pumped Potassium (K-Mag) and Proton Precession magnetometers. The company is recognized as the successful commercial developer of both the Overhauser and Potassium magnetometer / gradiometer. Moreover, its Proton Precession magnetometer / gradiometer is the latest technology system in its class.

Helping Professionals Meet their Application Needs

Quantum magnetometers and gradiometers are widely applied due to their ease-of-use, low cost of surveying, and data quality. Applications include Airborne Mapping, Archaeology, Earthquake Prediction, Education and Research, Environmental and Engineering, Mineral and Oil Exploration, Observatories, Unexploded Ordnance Detection (UXO), Volcanology and others.
