An apparatus for the automatic determination of water vapor sorption isotherm and isobares is described. Its main parts are a Cahn electrobalance and a gas circulating system. The gas can be held at constant dew points between – 85 and + 25 degree by an ultracryostal and an ultrathermostate and brings the sorbens to hygroscopic equilibrium.
