本文报导一种新型数字式自动光度滴定仪。它具有数字自动加液滴定功能和精密库仑滴定功能，不用预设滴定终点、不用滴定管、滴定度用时间计量、分析结果的典型相对标准偏差≤0．1％、操作使用十分简便。
This article reports a new type of digital automatic photometric titrator. It has the function of digital automatic titration and precision coulometric titration. There is no need to preset titration end point, no burette, titration time measurement, the typical relative standard deviation of the analysis result is ≤0.1%, and the operation is very easy to use.
