58. A calibration heater is indispensable for calibrating specific calorimeter vessels (once and for all) and for determining the heat capacity of the vessel contents (from transients, only the ratio of heat transfer capacity to heat capacity U-A/m-c can be obtained). As a calibration heater is an alien element in synthesis equipment, it is probably preferable to use the heater for calibration only, and to calculate the heat capacity of the contents from the batch recipe by means of a physical property estimator.
