UP-6125 VOC Formaldehyde Emission Test ChamberNowadays, the limited release of formaldehyde is a hot

Nowadays, the limited release of formaldehyde is a hot issue of environmental protection that is generally concerned by countries all over the world. Various interior decoration materials (such as wood products, furniture, wood-based panels, carpets, coatings, wallpapers, curtains, footwear products, building and decoration materials, automotive interiors) The release of VOC (Volatile Organic Compounds), formaldehyde and other harmful substances to the human body that come in contact with the human body is an important indicator to measure the quality of its products, especially for indoor and car products with densely placed and enclosed spaces. Inside, the cumulative concentration will be higher, which is more harmful to health. It is related to the pollution of the product to the environment and the impact of human health.

This product is suitable for the determination of formaldehyde emission of various man-made panels, composite wood floors, carpets, furniture, curtains, building decoration materials, automobile interiors and other materials, and provides a clean enclosed space without liquid water, while controlling The temperature, humidity, wind speed, relative pressure, and air exchange rate in the warehouse are used to simulate the pollutant release process of the product in a specific environment.
