  • Device and a method for permeation hydrogen measurements
    Patent number: 9857349
    Abstract: A method and a device for measuring a content of hydrogen absorbed by a metal workpiece by permeation in the form of hydrogen atoms are described. The device includes a probe with a mixing chamber accessible to an amount of hydrogen emanating from the workpiece, and communicating with an inlet port of a measurement gas. The device further includes a solid-state hydrogen concentration sensor pneumatically connected with the mixing chamber, a gas transfer means for forming a flow of a measurement gas from the inlet port to the sensor, and a processor means for processing a concentration signal of the sensor and for producing a parameter related to the interaction between the metal workpiece and the absorbed hydrogen.
