在容量分析中,滴定管的使用直接影响到分析结果的准确性。我们运用杨学田等的自动直读输液计量装置的原理,改装成滴定液电子自动计量装置。它易于操作、计量准确而迅速,有一定的推广价值。 图1 为该装置的全貌,图2为它的部件组合。 In capacity analysis, the use of burets directly affects the accuracy of the analytical results. We use the Yang Xuetian automatic direct infusion infusion device measurement principle, converted into titrant electronic automatic metering device. It is easy to operate, accurate and rapid measurement, there is a certain promotional value. Figure 1 shows the device in its entirety, and Figure 2 shows its components.
