Abstract

The utility model relates to an air particulate matter sampler. The air particulate matter sampler comprises a cylindrical sampling flask, wherein the flask comprises an air inlet and an air outlet; a self-suction type fan is arranged at the air inlet; a particulate matter mass concentration sensor and a particulate matter number concentration sensor are arranged on the inner side wall of the flask; adsorbing plates are arranged at the lower ends of the particulate matter mass concentration sensor and the particulate matter number concentration sensor; an air flow meter and a handle are arranged on the outer wall of the flask. The air particulate matter sampler disclosed by the utility model is simple in structure; firstly, the air flow meter is used for measuring the volume of air flowing through an air charging pipe in unit time, and the rotating speed of the fan is regulated as needed so that the haze air inflow of the air inlet can be conveniently regulated; the particulate matter mass concentration sensor and the particulate matter number concentration sensor are used for detecting the properties of particulate matters in the air by utilizing the light scattering theory; the adsorbing plates are used for adsorbing the particulate matters in the air; a single chip microcomputer is used for treating the particulate matters in the air and displaying the results; meanwhile, the cylindrical flask convenient to hold by a hand is adopted.

Description

Air granule sampler
Technical field
The utility model relates to air monitering technical field, is specifically related to a kind of air granule sampler.
Background technology
Constantly carry out along with the whole world is industrialized, environmental pollution is more and more serious, and various air-borne dusts are endangering the mankind's health, and in recent years, the international standard of PM2.5 and two dust of PM10 has been used to evaluate and test air quality.Much research has confirmed that particle can damage respiratory system and cardiovascular system, causes asthma, lung cancer, angiocardiopathy, inborn defect and dead too early.
