Details of calibration of a scanning calorimeter of the triple heat bridge type

It was shown that traditional procedure of measurement of heat capacity by the triple heat bridge method causes systematic error tied with a non-compensated asymmetry of a device. Two variants of calibration of triple heat bridge scanning calorimeters based on a ratio of signals from two cells are examined and compared to the conventional procedure of heat capacity measurements with DSC. Efficiency of calibration has been tested in experiments with rubidium nitrate and potassium chloride.
