Abstract
Two environmental test zones at different temperatures are separated by an insulated wall. A portion of the wall is rotatable and is designed to hold a test specimen thereon. By rotating this portion of the insulated wall, the specimen is exposed to different temperature zones in recurrent cycles. The two temperature zones are readily separable for ease in removing and installing test specimens.
