New automatic heat flow calorimeter.
A calorimeter was developed which is capable of measuring heats of reaction with high precision, without making use of a precision thermostat. In comparison with conventional heat flow calorimeters, the measuring time is reduced considerably by electronic means. The reproducibility is comparable to that of adiabatic calorimeters, while the operation is easier because no filling and weighing of water and temperature readings are necessary. The final result is indicated automatically.
