A method for measuring the surface temperature of a sensor in heat-transferable contact with a subject fluid employing an electrical, heating method in which the surface temperature is measured while passing an electric current through an electrical conductor included in said sensor. In this measuring method, the surface temperature is expressed as a function of a specific value inherent in the sensor the amount of the electric current, supplied to the electric conductor and the temperature of the electrical, conductor. The sensor is heat-transferably contacted with another fluid whose physical properties are previously known the surface temperature of, the sensor in contact with such other …
