Signals from the photodetectors are accumulated and processed by specialized software using correlation analysis. As a result, Segment-Bio makes a conclusion about the presence of bioaerosol in the air.
The UV radiation interacts with the aerosol particles in analyzed volume with further receiving the signal by the photodetectors.
The air jet is irradiated with two focused streams of UV flux.
The air enters through the concentrator into the pneumatic unit to form the air jet to be analyzed.
