Abstract

An apparatus which provides a temperature gradient within a small enclosed space is described. Provision is made for control of absolute humidity within the apparatus so that the same temperature gradient may be used with a variety of humidity gradients. The system of temperature measurement and recording and the operating characteristics of the machine are described.
