AMRA-Sr Ng® is the State of the Art among Aerosols Monitors. New advanced mechanical design solutions, Artificial Intelligence applied to spectra analysis and use of newest state of the art electronics allow superior performances of the Alpha/Beta and Gamma spectrometric measurement chains.
It is a budget friendly alternative to its higher performance version AMRA-Ge Ng® equipped with electrically cooled HPGe detector.
Thanks to the superior characteristics of its detector, the Gamma MCA is set-up for 4k channels, twice the number of channels normally usable with less performing scintillation detectors.
The innovative unique use of a crystal with very low intrinsic background and very high photonic yield makes possible at a reasonable cost the implementation of an industrial grade equipment with laboratory grade analytical performances on-line.
