Abstract
The invention is directed at a method of sensing hydrogen gas in a liquid comprising: providing a measuring device comprising a hydrogen sensing chamber and a palladium hydrogen sensor mounted in contact with said chamber, positioning a hydrogen permeable membrane between the liquid and the hydrogen sensor and creating a headspace, selectively providing air to the sensor headspace, thereby bringing air into contact with said palladium sensor to refresh the palladium, after the palladium sensor is refreshed shutting off air flow to the sensor headspace, bringing liquid into said chamber, allowing hydrogen to pass through the membrane and reach equilibrium, and reading the hydrogen concentration.
