Abstract
A hydrogen blistering corrosivity meter includes a cavity filled with a monitoring liquid. A liquid to be tested is separated from the monitoring liquid by a steel membrane. A device, which allows the volume of the measuring liquid to be monitored, is connected to the cavity. Dissolved hydrogen atoms, if any, formed by the test liquid diffuse through the steel membrane and enter the cavity, forming molecular hydrogen and causing an increase in volume in the measuring liquid which corresponds to the rate of corrosion activity.
