MX21B型数字式自动光度滴定仪的研制

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。

In this paper,the design of a new digital automatic photometric titrator is reported. The device works with functions of digital automatic photometric titration and precision coulometric titration. It doesn't need to be set up end point absorption in advance. Titre is indicated by timer. Analytical data is accurate and reliable(RSD≤0. 1 % ),and it is simple and convenient to operate.
