1. A process for measuring an electrochemical activity of a slag layer (2) lying on a steel melt (3), using an electrochemical sensor which has a measuring cell (5) and a counter electrode (4), comprising immersing the measuring cell (5) and the counter electrode (4) in the steel melt (3), such that the measuring cell (5) and the counter electrode (4) are protected from contact with the slag layer (2), bringing the measuring cell (5) and counter electrode (4) into contact with the steel melt (3) to heat the measuring cell (5) and the counter electrode (4), and pulling the measuring cell (5) up into the slag layer (2) for carrying out the measurement, such that the counter electrode (4) is located in the steel melt (3) during the measurement.
