Differenzdruckmeßsystem zur Bestimmung der Permeabilität, der Sorption und des Diffusionskoeffizienten stoffdurchlässiger Materialien, dadurch gekennzeichnet, daß die für die Permeation maßgebenden Parameter wie Permeabilität, Diffusionskoeffizient und die Sorption durch eine Meßanordnung bestimmt werden können, die auf der Bestimmung von Differenzdrücken, mittels eines elektronischen Differenzdrucksensors, zwischen dem Druck in einer zur Umgebung hin abgeschlossenen Meßzelle und dem Druck einer Referenzatmosphäre beruht. Ein Probenstück wird derart in der Meßapparatur eingebracht, daß dieses für vorhande Atmosphären eine permeable Barriere darstellt.Differential pressure measuring system for determining the permeability, the sorption and the Diffusion coefficients of permeable materials, characterized, that the parameters determining the permeation such as Permeability, diffusion coefficient and sorption through a measuring arrangement can be determined based on the determination of differential pressures, using an electronic Differential pressure sensor, between the pressure in one to the environment completed measuring cell and the pressure of a reference atmosphere. A sample is placed in the measuring apparatus in such a way that it is used for existing atmospheres represent a permeable barrier.
