Technical Field

[0001] The utility model relates to the field of environmental monitoring, in particular to a gas sampling auxiliary device for environmental detection. Background Art

[0002] Environmental testing refers to the systematic, continuous or regular monitoring and evaluation of various factors in the natural or artificial environment to determine the environmental quality, grasp the environmental pollution status, and provide a scientific basis for environmental management and protection. The objects of environmental testing include pollutants in various environmental media such as atmosphere, water, soil, noise, radiation, etc. When sampling gas cylinders for environmental monitoring, it is usually necessary to use corresponding auxiliary devices to collect the collected gas samples. The existing auxiliary devices usually use sampling bottles to accommodate gas samples in the process of collecting gas samples. However, since most of the gas sampling is done outdoors, the number of sampling bottles that the testers carry with them is easily limited, and carrying sampling bottles is not convenient for testers to exercise outdoors. Therefore, we propose a gas sampling auxiliary device for environmental testing to solve the above problems. Utility Model Content
