Sampling bag method
Inquire productEnvironmental chamber can provide standard testing environment(such as appointed temperature,relative humidity,air exchange rate and airflow rate)of simulaate real indoor environment,and test the pollutant release rate and release properties of various indoor materials and products.
Then it can;
- Confirm the influence of environment variables on the release rate and release properties of materials and products;
- Grade materials and products according to their release properties;
- Develop and validate the proposed model of indoor air pollution;
- Evaluate indoor air quality(IAQ)according to the data and proposed model of indoor pollutants;

The process of the test of pollutant release with the environmental chamber can be summarizd as: putting materials and products or their samples in the test chamber, and adjusting environmental conditions such as temperature in the chamber, relative humidity and air exchange rate; sampling at the exhaust port or the inside of the environmental chamber; adopting appropriate methods to analyze gas samples and identify major pollutants and the changes in their concentration with the time; then confirm the release rate and release properties of materials and products according to the measured concentration.
