ZD-2型自动电位滴定计,它可单独作为酸度计使用,用来测定pH值和mV值;若与DZ-1型滴定装置配套使用,可适于自动酸度滴定和自动电极电位控制。ZD-2型的测量部分(即酸度计部分)系采用机械振子调制式直流放大器线路;滴定部分系采用一组开关电路,即所谓“e-t”转换器,它把电极所测到的直流讯号和预定终点电位的差值e转换成短路脉冲t的输出。当e愈大,滴管滴下的溶液就愈多,当e=0,即溶液电位达到给定值
ZD-2 automatic potentiometric titrator, which can be used alone as a pH meter, used to determine the pH and mV values; if used with the DZ-1 titration device, suitable for automatic acid titration and automatic electrode potential control. ZD-2-type measuring part (ie, pH meter part) is the use of mechanical oscillator modulation DC amplifier circuit; titration part of the Department of a group of switching circuits, the so-called “et” converter, which measured the electrode DC signal and The difference e of the predetermined end potential is converted to the output of the short-circuit pulse t. When e is larger, the more dropper solution is, when e = 0, the solution potential reaches a given value
