FIELD: thermal physics. SUBSTANCE: thermal wall is arranged on the base of detector-heater in working calorimetric cell, directly in reaction vessel. The detector-heater permits to improve speed of operation of the calorimeter significantly and to indicate intensive heat releases due to compensation of the releases by rejecting electric power in wall heater. In order to indicate total thermal effect the heater is installed in standard cell; change in electric power of the heater is proportional to measured heat release. Control system is provided with the device that permits to turn heat wall off when heat release drops and to change to compensating measurement mode due to Peltier effect in compensation thermal batteries. EFFECT: improved speed of operation; widened range of heat release to be indicated and thermal effects. 2 dwg
