Gamma Surveyor Vario

as a 2048-channel geophysical gamma-ray spectrometer, includes all needed features and accessories for field, borehole and carborne survey with K, U, Th assays and dose rate measurement. Its easy operated control unit with attachable wirelessly coulpled compact probe allows to create a cost effective assembly regarding required accuracy and speed of measurement. The instrument works with either natural or artificial isotope spectrum stabilization, which is useful especially for quick and reliable measurement at very low gamma activities.
