Monitoring oxygen levels in metal processing and treatment furnaces
Modern metallurgical processes rely on controlled atmospheres to have protective or reactive effects on the metals being treated. Monitoring oxygen levels increases efficiency in the combustion control of a furnace and indicates the oxidizing potential of a controlled atmosphere. Excess of oxygen can result in reduced product quality or degradation of the product properties e.g. through oxidation. This means that the final product cannot be sold at the desired price or must be scrapped.
