New devices for measurement of hydrogen permeability in steels using electric resistance sensors have been assessed. Diffusion coefficients of two types of advanced high strength steels obtained with the traditional electrochemical permeation technique using the Devanathan–Stachurski permeation setup and the novel techniques are compared. The EPT technique is found to be more appropriate for laboratory assessment of hydrogen permeability due to generally better control over the experiment and data evaluation. The novel setups can be a good choice for comparative hydrogen measurements in real environments, including atmospheric ones, because of simpler sample preparation and small size of hydrogen probes.
