ZD-2型自动电位滴定计和DZ-1型滴定装置配套使用,可以完成多种电化学反应的自动滴定,前者又可单独作酸度计或电位差计用,操作方便,因而许多化验室都置有这套仪器。故障现象 ZD-2单独使用一切正常,也可以设置终点电位。DZ-1可进行手动操作,防过滴延时功能也正常。联机使用时,不能进行自动电位滴定。故障分析由ZD-2电原理图可见,自动电位滴定功能是由电位取样电路和e-t转换电路组成的。取样电路把测
ZD-2 automatic potentiometric titration and DZ-1-type titration device supporting the use of a variety of electrochemical reactions can be completed automatically Titration, the former can be used alone as a pH meter or potentiometer, easy to operate, so many laboratories are Set this instrument. Symptom ZD-2 alone use everything is OK, you can also set the end potential. DZ-1 can be manually operated, anti-drop delay function is also normal. When used online, automatic potentiometric titration can not be performed. Fault Analysis ZD-2 can be seen from the principle diagram, automatic potentiometric titration function is composed of potential sampling circuit and e-t conversion circuit. Sampling circuit to measure
