VOC emission test chamber can provide standard testing environment such as temperature humidity, air exchange rate and airflow to simulate real indoor environment to test the pollutant release rate and release properties of various indoor materials and products.
Features
1. Controls environmental conditions(Temperature, Relative Humidity, Air changes per hour and air velocity) inside the test chamber 1m³， 3m³ or other volumes optionally available
2. Prevention of contamination from the surrounding environment
3. Minimal adsorption effects
Applicable Standard
It is mainly used to detect the amount of formaldehyde and VOC released from interior decoration materials, decoration and decoration materials, wood-based panels, wood products, and other products. According to indoor pollutant data or prediction model, the indoor air is evaluated by comprehensive environmental indicators.
