Cosasco hydrogen probes detect hydrogen gas by the simple hydrogen pressure increase produced in an artificial cavity in the steel, i.e. the same mechanism as hydrogen blistering. The pressure build-up is directly proportional to the flux of atomic hydrogen, which can be determined by implementation of the ideal gas law. If the volume of the hydrogen probe cavity and the cross-sectional area across which diffusion is occurring is known, determination of the flux is a simple calculation.
