摘　　要：报道了一种新型数字滴定仪，它由马利奥特恒流器、石英计时器、目视滴定控制器、瞬时滴定控制器和磁力搅拌器构成。采用马利奥特恒流器和数字石英计时器计量标液用量，具有电路简单、制造容易、造价低廉、性能优良和操作简便的特点。瞬时滴定控制器可准确地控制滴定终点，使分析结果准确可靠。实际考察结果满意。he design of a new digital titration instrument is reported in this paper. The instrument is composed of Mariotte constant current titrator, digital quartz timer, colorimetric titration controller, instantaneous titration controller and magnetic stirrer. The end point of titration is controlled by instantaneous titration controller and titre is measured by Mariotte constant current titrator and timer. The new instrument provides the features of simple in circuit, high performances with low cost and convenient to operate. The analytical results obtained are accurate and reliable.
