System and method for monitoring hydrogen flux across the wall of a vessel or pipe, the system including a monitored volume for sealing an attachment to an outside surface of the wall of the vessel or pipe for collecting hydrogen escaping across the wall surface; a membrane selectively permeable to hydrogen in fluid communication with the monitored volume for permitting hydrogen to escape from the monitored volume in between the two at a defined rate such that hydrogen pressure equilibrium may be reached in the monitored volume for a given hydrogen flux across the wall surface of the vessel or pipe; a pressure measuring device in fluid communication with the monitored volume for measuring hydrogen pressure in the monitored volume; and a temperature measuring device in fluid communication with the monitored volume for measuring temperature in the monitored volume. |
