The meter is a real-time air quality monitor instrument used to monitor the concentration of PM2.5, humidity and temperature in the indoor environment. The meter convert the concentration of PM2.5 in the air into visual data, and evaluate the air quality comprehensively. Visual and audio alarm will be actived when the air quality reached a critical or alarm limit values. Particle pollution comes from many different type of sources.
