The Devanathan cell was developed for experiments to measure hydrogen permeation through membranes or a (steel) plate.
It consists of two glass vessels (diameter 100 mm, height 150 mm) with a PTFE-18/8/4 mm drain valve, a DN 40 side flange for inserting the membrane, a clamping device for sealing the flange, polypropylene lids, two counter electrodes made of platinum-coated titanium, and two reference electrodes, as well as additional holes of your choice (if required).
If this membrane is replaced by a metal sample (e.g., sheet steel), the permeation of hydrogen generated in the sample in one measuring cell can be measured in the second cell.
The metal sample can also be loaded in a corresponding tensile testing machine.
The Devanathan cell is available in various sizes and in heatable and non-heatable versions
