Previous work has shown that it is possible to deposit thin carbon-film resistance thermometers which are sensitive, reproducible, and easy to calibrate in the temperature range 4 to 300°K; also, it is possible to discriminate between the liquid and gas phases of a fluid by applying an electrical power pulse to the film and sensing the transient response [1].
