To sustain an optocoupler's performance and to avoid failure, the temperature is limited by managing the heat transfer between the chip and the ambient atmosphere. 为维持光耦特性，避免失效，通过管理芯片和周围空气之间的热传递限制温度。
Stainless steel chamber.Water-jacketed heating method ensures a uniform temperature and also keeps temperature constant for a long time after power off. 独立限温报警系统，超过限制温度即自动中断，保证实验安全运行不发生意外。
