VOC formaldehyde release test chamber is suitable for volatile organic compound release sample equipment, used to determine volatile organic compound release,
total volatile organic compound (TVOC), benzene, toluene, xylene and ethylbenzene sum, carbon disulfide and formaldehyde and other harmful substances release test.
Formaldehyde, VOC (Volatile Organic Compounds), benzene, toluene and other components in TVOC are strong carcinogens recognized by the World Health Organization.
Long-term exposure to pollutants with excessive concentrations will seriously endanger people's health. The amount of pollutants released is tested and limited.
will help improve product quality and protect people's health.
Wood products, furniture, floors, carpets, footwear products, building decoration materials, automobile interiors and other materials that come into contact
with the human body will emit VOC (volatile organic compounds), formaldehyde and other harmful substances to the human body,
especially for If products are placed densely and in closed spaces indoors or in cars, the concentration will be higher after accumulation, which will be more harmful to human health.
This test chamber is an instrument and equipment used to simulate the release of VOC (formaldehyde) from products in an environment close to where people live.
It is used to test and evaluate the amount of harmful substances released in furniture, building materials, automobile interiors and other products.
