A temperature probe is disclosed for determining the temperature at which residual oils can be vaporized from cold rolled strip without producing free carbon. The probe includes an open ended first tubular member with a burner mounted at one end of the first tubular member for closing the end thereof so that the burner fires its products of combustion through the first tubular member and out the other end thereof. A closed end second tubular member concentrically receives the first tubular member to define an annular heat space therebetween and has an exhaust port in fluid communication with said annular heat space adjacent the burner. Insulation extends on the inside of the outer tubular member for a fixed distance thereof from the exhaust port and a water jacket adjacent the exhaust port provides a temperature gradient along the length of the tube coincident with the insulation to provide a steady state, temperature indicating device in which the temperature varies, as a gradient, along the length of the outer tube.
