智能光度滴定仪及其在酸碱滴定中的应用

Intelligent Photometric Titration meter and its Application in Acid-base Titration

由便携式光谱测定仪(PORS-15)和数字滴定管(DAB-1)组成的智能光度滴定仪实现了滴定过程的全谱适时监测,系统能根据三维滴定曲线自动判定滴定终点,自动给出测定结果。酸碱滴定的标准偏差为0.014mL。

The intelligent photometric titration meter consisted of portable spectrophotometer （PORS - 15 ） and digital auto- marie buret（ DAB - 1 ） realized the online monitoring of the titration progression to absorption spectrum. This system can calculate the titration terminal point and print the determination results automatically by three- vision titration curve. The standard deviation of the acid - base titration is 0.014mL.
