HT-1型数字式自动滴定仪由四个部分组成:(1)滴定器;(2)两级微分检出器;(3)控制器;(4)A/D转换器。此仪器可以用作电位滴定。终点可由预置电位法或两级微分法检出。本文着重介绍自动滴定仪的机械部件和电子线路。仪器的指标如下: 应用浓度范围:0.01～0.5N 滴定器误差:10.00±0.02ml 精确度:±0.1mv 数字显示:±600.0mv HT-1 digital automatic titrator consists of four parts: (1) titrator; (2) two differential detector; (3) controller; (4) A / D converter. This instrument can be used for potentiometric titration. End point by the preset potential method or two differential method detected. This article focuses on automatic titrator mechanical parts and electronic circuits. Instrument indicators are as follows: Application concentration range: 0.01 ~ 0.5N Titrator error: 10.00 ± 0.02ml Accuracy: ± 0.1mv Digital display: ± 600.0mv
