6. After-sales service commitment of odor online monitoring system

Reasons for purchasing the odor online monitoring system:

1Objective assessment of odor pollutant emissions

For production enterprises, it is inevitable to emit or leak a small amount of odorous pollutants during the production process. By installing an odor online monitoring system, the pollutant emissions can be continuously monitored 24 hours a day, and the over-standard alarm function in the system can be used to It is possible to detect and deal with excessive pollutants in a timely manner; by analyzing real-time data and historical data, we can summarize patterns, identify problems, improve corporate management levels, and ensure that pollutant emissions comply with national standards.

2Response to residents’ complaints

When an odor pollution accident occurs, enterprises that have installed an odor online monitoring system can take timely response measures to reduce the hazards of the accident, give residents a proper explanation, and improve the harmonious relationship between enterprises and residents; the environmental supervision department uses the odor monitoring system to Conduct on-site monitoring of sudden odor pollution accidents, obtain monitoring results immediately, inform enterprises and residents of the pollution situation on-site, and improve the credibility of environmental protection departments.

3 Investigation of pollution sources of odor accidents

Enterprises that have installed an odor online monitoring system can use the odor monitoring data combined with meteorological monitoring data to exclude or determine whether they are pollutants emitted by themselves; the environmental supervision department can use the odor monitoring system to establish a database of characteristic pollutants of enterprises within their jurisdiction. When a pollution accident occurs, polluting enterprises can be quickly identified by combining meteorological data.

4. Improve public image

4.1 Enhance corporate public image and increase brand value

Through the installation of the odor online monitoring system, we can effectively reduce the occurrence of odor pollution accidents, live in harmony with surrounding residents, and respond to the policy of "lucid waters and lush mountains are valuable assets" strongly advocated by the country. Supplemented by appropriate media promotion, it can effectively enhance the corporate image, increase brand value, and can also become a bonus for corporate financing.

4.2 Improve the credibility of environmental protection authorities

The timely handling of odor pollution accidents has always been one of the headaches for environmental protection regulatory authorities. In the past, when there was a lack of effective monitoring methods, residents often mistakenly believed that the competent authorities were inactive and shielding polluting enterprises; while production companies believed that regulatory authorities were stuck in their efforts. Arbitrary fines will have a negative impact on the government's image. Through the use of odor monitoring analyzers, monitoring data can be clearly provided on site, effectively improving the credibility of regulatory authorities.
