Description

Technical Field

[0001] The utility model relates to air monitoring equipment, and more specifically to the structure of a portable air monitoring equipment. Background Art

[0002] Air monitoring equipment is a device used to monitor air conditions. It can help people understand air conditions and assess air quality, thereby preventing and controlling air pollution. Air monitoring equipment is an important tool in the environmental protection industry and can provide strong support for environmental protection. For example, air quality monitors can monitor SO2, NO x The smoke monitor can monitor the flow rate and moisture content of smoke and PM10 and other pollutants and particle content. The toxic and harmful gas monitor can monitor Cl2, H2S, SO2 and combustible gases. The spectrophotometer can monitor cyanide, ammonia nitrogen, aniline and other highly toxic substances.

[0003] Air monitoring equipment usually has fixed and mobile types. Fixed air monitoring equipment is larger in size and is usually installed in air quality monitoring stations to monitor air quality over a long period of time. Mobile air monitoring equipment is smaller in size and is usually used for rapid, temporary monitoring of air in certain locations. It is mainly used for air quality inspections or monitoring of sudden pollution accidents.

[0004] When mobile air monitoring equipment is used in different environments, it needs to be at a certain height or angle to ensure that the air it contacts is fluid. Existing mobile air monitoring equipment has no mounting bracket, which makes it inconvenient to install and use. When used, it is usually placed on the ground or on a temporary support device such as a table for support. However, placing the air monitoring equipment on the ground will lead to inaccurate test results. If it is placed on a temporary support device, it will be installed loosely and easily fall and be damaged, affecting work efficiency.

[0005] The utility model aims to solve the problem that the existing mobile air monitoring equipment is inconvenient to install, which affects the detection accuracy and detection efficiency. Utility Model Content
