- Abstract:
- In APMF2011, we introduced a simple way by building a two-layer insulation chamber with two mass comparators inside to have small temperature variation in our laboratory. In this paper, we will introduce a economic method by adding a simple active control unit on the aluminum chamber to control the temperature inside the chamber at (20 ± 0.1) °C nearly, while the room temperature of the air-conditioning laboratory is active controlled at (21.5 ± 1.5) °C. Using this method, the transient phenomenon of temperature was observed.
