The temperature changes after moisture jumps on different material surfaces were demonstrated in laboratory tests. These phenomena (latent heat effects) also occur with gradual moisture changes but less pronounced amplitudes. Especially measurements in field tests, therefore, require methods that can record very small temperature differences without environmental influences. The measuring technique developed for this purpose shows promising results for measurements on different wood surfaces and might allow conclusions about the transient hygroscopic behavior. Although, we found limitations in the measurement method in the case of increased air velocities on the component surface.     «
