Description

TECHNICAL FIELD

[0001] The present application relates to the field of environmental monitoring, more particularly, to a multifunctional outdoor air quality monitor. BACKGROUND

[0002] The air quality monitor is a new scientific product developed based on the principle of constant potential electrolytic sensor for detecting polluted gas, the principle of light scattering for detecting dust, and the mature international electronic technology and network communication technology. The instrument can simultaneously monitor the concentrations of gas and inhalable particulate matter and display them on the same display screen. One instrument can simultaneously monitor four parameters. The instrument works in an automatic sampling and automatic analysis mode. The measured concentration is directly displayed on the display screen, and the daily average and monthly average values are automatically calculated. The monitor can store 30 days of monitoring data.

[0003] The outdoor air quality monitor is usually fixed on a fixed rod by screws. During the operation of the air quality monitor, routine maintenance includes replacing consumables, repairing circuits, calibrating flow, calibrating the point and zero point, calibrating the dynamic calibrator, analyzing and troubleshooting common faults, etc.

[0004] In the prior art, the air quality monitor is generally fixed by screws. When working in the outdoor environment for a long time, the screws are prone to rust, which is inconvenient for disassembly in the later stage. When monitoring the air in a place where gas may leak, it is necessary to install the air quality monitor nearby. However, the height of the place where gas may leak is not the same. Therefore, a fixed rod with a suitable height is needed to install the air quality monitor. In addition, the air quality monitor at a high place is not convenient for routine maintenance. After a long period of use, the side of the sample gas inlet is gradually blocked by dust in the air, which prevents the monitor from obtaining external air for detection. Therefore, it is generally necessary to open the air path for cleaning on a monthly basis.

[0005] Therefore, a multifunctional outdoor air quality monitor is proposed. SUMMARY
