ABSTRACT:
Devices relating to a psychrometer employing an infrared thermocouple aimed at a wet surface, and another infrared thermocouple aimed at a dry surface, are described. The wet surface is continuously supplied with liquid, for example, H.sub.2 O. The infrared thermocouple which is aimed at the wet surface detects evaporative heat loss instantaneously at the wet surface as it occurs, without coming into contact with the wet surface.
