DIFFERENTIAL SCANNING CALORIMETER HAVING LOW DRIFT AND HIGH RESPONSE CHARACTERISTICS

The sample temperature is roughly controlled according to a program temperature by a furnace temperature controller, and at the same time precisely controlled by a detector temperature controller. Also, if a temperature difference occurs, the supply powers to heaters separately provided close to the sample and reference are adjusted such that the temperature difference is returned to zero by a differential heat compensating circuit, outputting a difference in supply power as a differential heat flow.
