How AQM-09, AQMS-09 and OC-9200 Deliver Reliable Data in Different Environments
Accurate air quality data is the foundation of environmental management. However, many users discover that monitoring results become unstable during rainy seasons, in coastal regions, or in high-humidity environments.
One of the main reasons is humidity.
Whether measuring particulate matter or gaseous pollutants, excessive moisture can influence sampling, sensor response, and ultimately data accuracy. Therefore, humidity compensation has become an essential feature in professional air quality monitoring systems.
How Does Humidity Affect Air Quality Monitoring?
High humidity can influence monitoring in several ways:
- Water vapor may increase the apparent concentration of PM2.5 and PM10.
- Moisture can condense inside sampling chambers.
- Electrochemical gas sensors may experience signal drift.
- Long-term exposure to humidity accelerates contamination of optical components.
These factors may lead to inaccurate readings and unstable monitoring performance.
Our Solution: Automatic Heating & Humidity Compensation
To minimize humidity interference, Oceanus monitoring systems are equipped with an automatic heating and humidity compensation module.The collected data can be transmitted to 4G cloud platform in real time for remote monitoring and analysis.
Heating & Dehumidification in PM2.5 Monitoring
Heating and dehumidification technology is primarily used in high-precision environmental monitoring systems to eliminate the influence of humidity on measurement results. Its purpose is to improve data accuracy rather than to purify indoor air.
This technology helps maintain stable sampling conditions, reduces condensation inside the sampling path, and improves measurement consistency under changing weather conditions.
Combined with industrial-grade sensors and intelligent data correction, the system provides more reliable environmental monitoring results throughout the year.
Choosing the Right Monitoring Solution
| Application | Recommended Model |
| Urban Air Quality | AQM-09 / AQMS-09 |
| Environmental Protection Projects | AQMS-09 |
| Government Monitoring | AQMS-09 |
| Industrial Parks | AQMS-09 |
| Construction Sites | OC-9200 |
