在工业电位测量中多采用饱和甘汞电极作为参比电极。由于被测液中往往有悬浮的固体,杂质,因而连续使用会使电极盐桥堵塞,导致盐桥内电解质溶液的渗漏中断;加之工业上反应器内的压力常高于外界大气压,致使被测液反渗漏到盐桥内的电解质中,这样由于改变了盐桥内电解质的组成,使参比电位发生变化。为此作者制成了一种无渗漏参比电极,这种参比电极的特点在于它的盐桥端部的结构和材料 In the industrial potential measurement more use of saturated calomel electrode as a reference electrode. As the measured fluid often suspended solids, impurities, which will continue to use the salt bridge electrode block, resulting in salt bridge electrolyte solution leakage interruption; combined with industrial reactor pressure is often higher than the outside atmospheric pressure, resulting in being Anti-seepage fluid into the salt bridge within the electrolyte, so as to change the salt bridge electrolyte composition, the reference potential changes. To this end, the author made a leak-free reference electrode which is characterized by the structure and material of its salt bridge ends
