The BW-BAA810 bioaerosol alarm is based on the Mie scattering method and UV induced fluorescence method to detect the particle size of bioaerosols. It is excited by three light sources and detected through multi-channel fluorescence bands, which can distinguish between living and non living organisms. It can continuously and real-time monitor the concentration changes of biological factors (bacteria, spores, viruses, toxins, etc.) in the air, and alarm for biological factors that reach dangerous concentrations. It is widely used in fields such as healthcare, biosafety, industrial production, public places, as well as schools and educational institutions....
