Product Purpose
Environmental chamber can provide standard testing environment(such as appointed temperature,relative humidity,air exchange rate and airflow rate) or simulate 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 pollutions;
• Evaluate indoor air quality(IAQ) according to the data and proposed model of indoor pollutants;
