Abstract

This paper describes the development of a dew-point apparatus and a technique for its use in determining the relative humidity inside water vapor transmission test cabinets. Results reported define the cyclic nature of the temperature and humidity conditions existing in the test atmospheres. The apparatus and method yield results that are accurate to a high degree.
