Small Formaldehyde VOC Environment Test Chamber
Suitable industries: wood products, furniture, floors, carpets, footwear products, building decoration materials, automotive interiors and other materials.
Formaldehyde, benzene, toluene and other components in VOC (volatile organic compounds) are strong carcinogens identified by the World Health Organization. Long-term exposure to pollutants exceeding the standard concentration will seriously endanger people's health. The release of pollutants should be tested and limited. It will help to improve product quality and protect people's health.
Small Formaldehyde VOC Environment Test Chamber is mainly used to detect the formaldehyde and VOC emission in interior materials, decoration materials, man-made panels, and their wood products; at the same time, it can also test the VOC emission of other products. Comprehensive environmental index evaluation of indoor air quality based on indoor pollutant data or prediction models.
