恒温槽灵敏度实验之简易精密温度控制装置的研制

Development of a simple and minute device designed for controlling the temperature for the sensitivity experiment of constant temperature tank

根据本科生课程化学基础实验中恒温槽灵敏度实验中的温度控制装置进行改造,开发出一种简易、耐用且精密可靠的温度控制装置,从而研制了一种适于高精度低温实验的新型低温恒温槽。经过实验可知,该恒温槽灵敏度约为±0.0065℃。

According to the requirements of the undergraduate chemical basic experiments courses,we reconstructed the temperature control device which used in the sensitivity experiment of constant temperature tank,and developed a simple,reliable,durable and precise temperature control device,which can be used as a low-temperature experiments for the new high-precision and low-temperature constant temperature tank.Experimental results shows that the sensitivity of the tank is about ± 0.0065℃
