Currently, standard reference electrodes are affected by soil environmental conditions, which can easily lead to inaccurate reference potential and a shorter service life due to factors like drought or humidity. Our company, through relentless efforts, has independently developed the KR2 salt bridge patent-type long-lasting polarization probe. Compared to similar foreign products, it boasts a novel structure, good stability, and robust reliability. It has a long service life, is easy to carry, and is suitable for field applications. Furthermore, it measures and standardizes the reference potential using CSE (copper/copper reference electrode), commonly used in China's soil cathodic protection projects, instead of SCE (standard calomel electrode), which is commonly used with imported polarization probes. Therefore, it is a new generation reference polarization probe that is more suitable for China's national conditions.

Primarily used for matching intelligent test piles, serving as long-life reference electrodes, as well as for environmental applications such as tank bottom and coastal pipeline test piles.
