A large chamber for measurement of VOCs emission rates from building materials and furniture was developed. The chamber system is consisted of a stainless inner chamber operated slightky above atmospheric pressure, an outer chamber, which controls temperature of the inner chamber, and an air control unit, which supplies purified air. It is able to control humidity and ventilation rate of the inner chamber. The measurement of YOCs emission rates from system kitchen units were performed using the large chamber.
