Four conventional parameters for online odor monitoring: NH3, H2S, TVOC, and OU value;

Power supply system: Mains power supply conversion system

Gas collection system: The air in the environment is drawn into the gas collection chamber (sniffing bag) for detection and analysis through a sampling pump and a gas collection rod (including a flow control unit);

Monitoring system: gas sensor detection module, meteorological parameter detection module, responsible for the identification and analysis of different odor components in odor samples; sensor array design, integrated multi-gas cross-interference algorithm, temperature and humidity compensation algorithm control system: the control unit collects the detection data of each sensor, and uses the big data model to analyze and calculate to obtain accurate data;

Display system: presents the collected and processed data of each monitoring factor in an easy-to-understand manner; the chassis is integrated with a 7-inch high-definition color screen, which can be equipped with an external LED display screen or a large-screen control center;

Transmission system: The transmission unit uses DTU or data acquisition instrument (2-channel 232 interface, 3-channel 485 interface, 2-channel Ethernet interface, other interfaces are optional), transmission protocol J212; data can be displayed on the smart environmental protection supervision platform, the platform specified by the demander, the environmental protection bureau platform, etc.

3. Features of Odor gas online monitoring system

6. After-sales service commitment

Reasons to choose Odor gas online monitoring system:

1 Objectively evaluate odor pollutant emissions

For manufacturing enterprises, the emission or leakage of a small amount of odorous pollutants is inevitable during the production process. By installing the Odor gas online monitoring system, pollutant emissions can be monitored continuously for 24 hours. By using the over-standard alarm function in the system, pollutant over-standard situations can be discovered and dealt with in a timely manner. By analyzing real-time and historical data, summarizing patterns, discovering problems, improving enterprise management level, and ensuring that pollutant emissions meet national standards.

2. Response to residents’ complaints

When an odor pollution accident occurs, companies that have installed the Odor gas online monitoring system can take timely countermeasures to reduce the severity of the accident, give residents an appropriate explanation, and improve the harmonious relationship between companies and residents. Environmental regulatory departments use the odor monitoring system to conduct on-site monitoring of sudden odor pollution accidents, obtain monitoring results immediately, and inform companies and residents of the pollution situation on site, thereby improving the credibility of environmental protection departments.

3 Investigation of odor pollution sources

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

4. Improve public image

4.1 Enhance the corporate public image and increase brand value

Through the installation of Odor gas online monitoring system, the occurrence of odor pollution accidents can be effectively reduced, and the surrounding residents can coexist harmoniously, responding to the national policy of "Green water and green mountains are gold and silver mountains". With appropriate media publicity, it can effectively enhance the corporate image, increase brand value, and also become a plus point for corporate financing.

4.2 Improve the credibility of environmental protection authorities

Timely handling of odor pollution accidents has always been one of the headaches for environmental protection regulatory departments. In the past, when there was a lack of effective monitoring methods, residents often mistakenly believed that the competent authorities were inactive and shielded polluting enterprises; while production enterprises believed that the regulatory authorities were blocking them and imposing fines indiscriminately, which had a negative impact on the government's image. Through the use of odor monitoring and analyzers, monitoring data can be given on site, clearly and effectively improving the credibility of regulatory departments.
