Portable to change solution and polish copper electrode at any time, making potential easy to achieve stability and accuracy.

The long-term copper sulfate reference electrode is often affected by the production process and the use of the environment, the requirement of buried in the perennial wet soil, if fully immersed in water or dry soil will affect the accuracy of the reference electrode, resulting in a large deviation.

Solid zinc reference is also related to the use environment. Once the soil is dry, the reference potential of zinc is positively shifted, and the reference change will lose its significance as a reference. The long-term reference electrode needs to be improved continuously. The choice of power supply: the external current cathodic protection mostly used in foreign countries rectifier, because the soil medium, humidity change is not frequent, rectifier fully meet the requirements of cathodic protection. It is simple in structure, easy to maintain and cheap in price.

The potentiostat is suitable for the protection of constantly changing media such as ocean tide and stray current interference, and the potentiostat must rely on the long-acting reference electrode feedback signal, if the reference electrode is not accurate, it will affect the output of the potentiostat, so it is recommended to give priority to the rectifier in the design.
