ABSTRACT:
Heat fluxmeter incorporating a row of thermistors, whose electrical resistance varies significantly with the temperature and which are arranged on the outer surface of the container for accurately measuring the temperature thereof. The range of temperatures in the vicinity of the container is determined by means of a second row of thermistors. It is possible to deduce therefrom the heat flux leaving the container, i.e. the power emitted by the calorigenic material contained therein. The considerable sensitivity of this meter makes it possible to use it without excessively disturbing the thermal equilibrium so that the measurement can be carried out in a very short time.
