Formaldehyde Emission Test Chamber

The internal surface of chamber is made using SUS# 304stainless steel.
This formaldehyde emission test chamber is a great choice to test formaldehyde, acetaldehyde, benzene derivatives and other low boiling point VOCs. However, it’s unsuited for high boiling point VOCs and polar compounds, like tetradecane and 4-phenyl-1-cyclohexene.

Application of Formaldehyde Emission Test Chamber
1. The emission chamber offers standard testing environment to determine the hazardous gas emission rate and emission characteristics of interior decoration materials and products. Based on the results, we can:
• Determine the impact of environmental variables on the emission rate and emission characteristics.
• Classify the level of products and materials according to the emission characteristics
• Develop and adjust indoor air pollution models
• Evaluate the IAQ (Indoor Air Quality) according to the pollution data and test report
2. As being a functional equipment of formaldehyde emission test, the emission chamber finds a wide application in interior decoration, office furniture, engineered wood, carpets, plastics, leather, textile, toys and more.

Testing Methods
1. The air is first processed by compressor to remove solid particles, formaldehyde and volatile organic compounds, and then enters into the test chamber.
2. The climate chamber is designed with an air jacket for conditioning the temperature in testing chamber.
3. By adopting dew point method, the humidity of climate chamber is well regulated and controlled.
