An understanding of the mechanisms by which water molecules are held within a substance or at its surface, either by physical
or chemical processes, is of importance in the formulation, preparation and storage of a wide variety of substances. The traditional
experimental techniques which have been used to make measurements on samples exposed to specific levels of relative humidity,
(e.g. using desiccators containing saturated salt solutions), are slow, laborious, inaccurate, and provide a limited amount
of data. This paper describes the conception, operation, and facilities of a new system which by employing recently developed
electronic components and transducers, significantly advances the performance capability for moisture sorption analysis.
