The ability to control thermal drifts is essential in operating a calorimeter. We investigated a thermal enclosure, which envelops the calorimeter with temperature‐regulated air, thus thermally isolating the calorimeter from the room. The desired temperature in the enclosure is controlled by a control circuit and a thermoelectric device, which works as a Peltier effect heat pump. In this report, the details of the enclosure design and construction are presented with actual performance evaluations.
