Abstract
A hollow iron capsule of annular shape having an interior layer of Fe.sub.0.947 0 and a near absolute internal vacuum is submersed within a molten metal with the inner chamber of the capsule connected to a pressure sensor. Carbon present in the molten metal diffuses through the capsule wall and reacts with the Fe.sub.0.947 0 layer to generate a CO.sub.2 --CO gas mixture within the internal chamber. The total absolute pressure of the gas measured by the pressure sensor is directly proportional to the carbon activity of the molten metal.
