Along with expanding economy, the raising of life taste, increasing people starts to focus on healthy and environmental protection, and new family fits up
After Hao, outside the measures such as basic ventilation and placement remove formaldehyde plant, charcoal bag, a lot of people also can use air quality to examine
Survey instrument and carry out complete detection Air Quality, protect the health of anemia of pregnant woman, child, old man and house person comprehensively, and PM2.5
Polluting and caused extensive concern and discussion especially, in March, 2012, PM2.5 lists " the ambient air quality mark of new revision for the first time in
Accurate ", PM2.5 causes the great attention of people in China, and the documentary film " under the firmament " of environmental conservation is especially by people
To haze, the concern to PM2.5 is pushed a new climax, PM2.5 i.e. fine particle to, is referred to aerodynamic in surrounding air
Equivalent diameter is less than or equal to the particulate matter of 2.5 microns, and it can be suspended in air long period, and content concn is more in atmosphere for it
Height, just represents air pollution the most serious, and PM2.5 particle diameter is little, containing a large amount of poisonous and harmful substances and atmospheric residence time
Length, fed distance are remote；Meanwhile, fine particle is bigger to other pollutant of hazard ratio of health, because diameter is the least, enters
The position entering respiratory tract is the deepest, after fine particle enters human body alveolar, directly affects the ventilatory function of lung, makes body easily be in
Anaerobic condition, therefore, fine particle is the biggest on the impact of health and atmosphere quality.
The file of Patent No. CN105424565A discloses a kind of hand-held PM2.5 detector, belongs to environmental project skill
Art field.This detector includes: housing, PM2.5 detecting head, central processing unit, effusion meter and battery；The two ends of housing are made respectively
