TES 5322 PM2.5 Air Quality Monitor

 TES 5322 PM2.5 Air Quality Monitor converts the concentration of PM2.5 and VOCs 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.
Fine particle (2.5 micrometers in diameter and smaller) include power plants, industrial processes, vehicle tailpipes, wood stoves, and wildfires.
Coarse particles (between 2.5 and 10 micrometers) come from crushing and grinding operations, road dust, and some agricultural operations.
Particle pollution is linked a number of health problems, including coughing, wheezing, reduced lung function, asthma attacks, heart attacks and strokes.
It also is linked to early death.
Some people may be at greater risk from particle pollution.
