长效硫酸铜参比电极
Long-Acting Copper Sulfate Reference Electrode
产品定义
Product Definition
硫酸铜参比电极是阴极保护系统中重要的组成部分。参比电极内部由纯铜线圈和饱和硫酸铜溶液组成,外壳采用微渗透陶瓷罐。电极的电位稳定性好,应用广泛,多用于测量被保护金属构筑物的对地电位以及作为恒电位仪自动控制的信号源。
The copper sulfate reference electrode is an important component in the cathodic protection system. The interior of the reference electrode is composed of a pure copper coil and saturated copper sulfate solution, and the shell is a micro-permeable ceramic tank. The electrode has good potential stability and wide application, mostly used for measuring the ground potential of protected metal structures and as a signal source for the automatic control of the potentiostat.
