一、ZDJ—4型自动电位滴定仪的特点: 该仪器是多功能的滴定系统,能满足各种类型电位滴定的容量分析要求,除能进行自动滴定、空白滴定和手动滴定外,还具有一般离子计的基本功能,如斜率标定、直读浓度、一次添加和电位测定等。该机由于采用了性能优越的双高阻电位仪和高精度的滴定管,故具有输入阻抗高,电位稳定性好、控制精度高和重现性好等特点。(计算机系统和 First, ZDJ-4-type automatic potentiometric titrator features: The instrument is multi-functional titration system to meet the various types of potential titration capacity analysis requirements, in addition to automatic titration, blank titration and manual titration, but also have the general The basic functions of the ion meter, such as the slope calibration, direct reading concentration, once added and potential determination. Due to the use of dual-resistance potentiometer with high performance and high-precision burettes, it has the characteristics of high input impedance, good potential stability, high control accuracy and good reproducibility.
