Imatic system is a firmware based, automatic, low background, gas free alpha / beta counter designed for analyzing air filters and smearing or sliding samples. The imatic system distinguishes radon isotopes and their descendants from the transuranium and fission product materials on the sample. It uses solid-state silicon pips detectors for alpha and beta detection; It can run continuously for more than six hours with the built-in battery and is completely independent. Imatic system represents a major technological breakthrough in aerosol analysis and is widely used in environmental protection, nuclear power, nuclear industry and other fields.
