Abstract: Method and apparatus for continuously measuring the oxygen and carbon contents of a molten metal, particularly of iron in a BOF furnace. A wire containing as a component a metal which is a getter for oxygen continuously fed into the melt. A concentration cell is established and the EMF developed is used as a measure of oxygen content. Carbon content is a function of the reciprocal of the oxygen and is calculated therefrom. Automatic control over the oxygen feed results in automatic control over the carbon content. When the EMF of the cell is temperature dependent, means are incorporated for simultaneously measuring the melt temperature.
