Why Monitor CO2?
Indoor Air Quality (IAQ) is measure for the quality of air in interiors, the comfortable indoor environmental quality can make people feel fresh, work efficiency and good for the health. The CO
2 concentration is the important factor of good indoor air quality. People breath in oxygen and breath out CO2, nowadays people often close the windows to avoid noise and enjoy the comfort living and working environment provided by air-conditioning systems, which results in the fact that the indoor concentration of CO2 is far higher than outdoor average. With the high CO2 concentration and non- proper ventilation, people will feel headaches, dull, drowsiness, lose of concentration and correspond to the high levels of dust, chemicals and bacteria in the air.

PM2.5 Air Quality Meter Particle Counter AMF079        
 This product is mainly used to measure the concentration of particles in the air can be inhaled, which is what we usually PM2.5, incidentally, functional measurement of air temperature, humidity, the use of laser technology to measure, very sensitive.
Fine particulate matter, also known as fine particles, fine particles PM2.5. It refers to fine particulate matter in ambient air aerodynamic equivalent diameter less than or equal to 2.5 micron particles. It was suspended for a long time in the air, the higher its content concentration in the air, on behalf of the more serious air pollution. While the Earth's atmospheric composition PM2.5 only a few components in the content, but the air quality and visibility has important impact. Compared with coarse atmospheric particulate matter, PM2.5 particle size is small, a large area, active, easy incidental toxic and hazardous substances (such as heavy metals, microorganisms etc.), and long residence time in the atmosphere, transmission distance, thus a greater impact on human health and environmental quality of the atmosphere.
