ABSTRACT:
A probe for measuring the concentration of an impurity in molten iron is disclosed. The probe comprises three sensors. The first sensor measures the activity of the impurity element directly. The second sensor measures the activity of free oxygen. The third sensor measures carbon content. These values are used are used to give a compensated measure of the impurity element.
