Hydrogen Probes 6400

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.
