研究了用于海水介质中高稳定性的参比电极。实验测试了烧结温度、介质温度及介质纯度等因素的影响。结果表明，两种不同的烧结温度对电位稳定性无影响，介质温度对电极电位影响小，而介质纯度明显影响电极电位的稳定性。选用适宜的电极腔体能消除介质不纯引起的电极电位不稳，使参比电极精度达≤±０．０１ｍＶ／４ｈ，可作为水下阴极保护多功能检测装置用参比电极，也适用室内精密的测量工作。
A reference electrode for high stability in seawater media was studied. The effects of sintering temperature, medium temperature and medium purity on the experiment were tested. The results show that the two different sintering temperatures have no effect on the potential stability. The medium temperature has little effect on the electrode potential, while the medium purity significantly affects the stability of the electrode potential. The selection of suitable electrode cavity can eliminate the instability of the electrode potential caused by the impure medium, and the accuracy of the reference electrode can reach ≤ ± 0.01mV / 4h, which can be used as a reference electrode for underwater cathodic protection multi-function detection device, and indoor precision Measurement work.
