A method and apparatus for detecting the carbon potential of a gas atmosphere within a heat-treatment furnace. A sample of gas atmosphere is extracted from the furnace and while cooling it the carbon deposit temperature is measured by a measuring element having of a carbon deposit detecting tip and a thermocouple adapted to be inserted directly into the furnace to measure the carbon deposit temperature of the said gas atmosphere. A temperature control means is connected with the carbon deposit detecting tip for changing the temperature of said tip, and a recorder is connected with said thermocouple for recording the temperature at which the tip detects a carbon deposit. The internal temperature of the furnace is measured, and the thus measured temperature values are used to determine the carbon potential.
