This paper describes a measurement system to measure fundamental characteristics under endothermic and exothermic reactions using calcium chloride (CaCl_2) on chemical heat storage. In order to enable reversible chemical reaction, a measurement apparatus and method have been developed in this study. The apparatus consists of a reaction chamber and a steam chest. Measurands which become the target of the measurement are confined to temperature, vacuum pressure and mass. All measurands can be detected electrically by using a thermocouple, a differential pressure gage and a strain meter, and the automatic measurement by using a microcomputer is possible at real time. The pressure gage is independent of humidity in a measuring atmosphere. Furthermore, in mass measurement under vacuum conditions, the effect of fluctuations in temperature or pressure is removed by using the principle of parallel springs. Consequently, the measurement system is confirmed to be useful for measuring fundamental characteristics of chemical heat storage using CaCl_2.
