Description

technical field [0001] The invention relates to the field of gas sampling and measurement, in particular to a device for detecting the concentration of particulate matter in the air. Background technique [0002] Since the reform and opening up, China has focused on economic development, ignoring the environmental pollution problems brought about by the development process. Especially in the central, eastern and coastal areas, chemical plants have sprung up like mushrooms, but the pollutant discharge settings are uneven, and because some factories Various accidents caused by management negligence also pose a threat to the environment. [0003] At present, the testing equipment used by most factories is backward, requiring a lot of manpower and material resources, wasting corporate resources, and because of the problems of the equipment itself, the accuracy of the testing results is also questioned, which affects the healthy development of the company.
