Abstract:
A heat and moisture transfer characteristic measurement system for thin materials comprising means for forming a laminar air flow space on each side of a target sample material to be measured; a pair of air passage means for providing two types of air, each adjusted to have predetermined temperature and humidity values, one of said two types of air to pass through one of said laminar spaces and the other of said two types of air to pass through the other of said laminar spaces; and means for detecting temperature and humidity variations in each of said laminar spaces, one of said pair of air passage means being provided with two conditioned air supply units and a changeover device for switching between air supply units so as to instantaneously supply air having different temperature and humidity values; wherein a removable sample holder is provided between said pair of laminar spaces, said holder having an opening capable of causing the target sample mounted thereon to be exposed to any said laminar spaces.
