DESCRIPTION DESCRIPTION TECHNICAL FEATURES BAWS – 06 is designed and manufactured to issue a warning in response to terrorist and biological attacks or an unusual increase in biological contamination of urban and hospital areas. The device uses a vacuum pump which samples a 28.3 liter volume of the ambient air and simultaneously evaluates the particulate matter using UV LED. For this purpose, an optical cell is designed and produced. If a particle is exposed to biological radiation, fluorescent light is emitted from the particle and received by the optical receiver, then processed by the electronic analyzer. The device gives notice of unusual increase in biological particles through audio-visual signals.
