本文将DPC - 2B数字式低真空测压仪应用于基础化学的减压蒸馏操作等实验中 ,替代U型水银压力计 ,从而达到消除汞蒸气的污染 ,增加实验的安全性 ,在实验时读取数据更方便、更直观 ,操作更容易等目的。
In this paper, DPC - 2B digital low vacuum manometer is applied in the experiment of vacuum distillation of basic chemistry and so on, instead of U - mercury manometer, so as to eliminate the pollution of mercury vapor and increase the safety of experiment. Take data more convenient, more intuitive, easier to operate and so on.
