Hydrogen Probes

Hydrogen probes can be used to measure corrosion rate and to detect the diffusion of atomic hydrogen into materials. Many corrosion processes involve atomic hydrogen as a product of the corrosion reaction. Thus, by measuring the atomic hydrogen present, a corrosion rate may be determined. Hydrogen probes are more often used to detect the diffusion of atomic hydrogen into adjacent materials, such as pipe walls, as hydrogen-induced cracking may result. Hydrogen monitoring has been highly beneficial in oil refining and petrochemical industries due to the presence of hydrogen sulfide in such plants.
