海水的污染程度有时也会影响阳极的工作性能。

Sacrificial anodes are used for underwater metal structures, which are usually measured once every three months, mainly to measure the potential of each measuring point, anode output current and other values.
It should also be noted that the anode connecting the cable to the underwater structure metal should be checked regularly to avoid damage caused by waves and ships and be repaired in time.
When the protective potential of the structure against water is not negative enough, the anode shall be replaced, and other anodes shall be considered for inspection.
The other is fixed to underwater structures, so the output current cannot be measured, and can only be measured according to the protection potential.
The pollution degree of seawater sometimes affects the working performance of the anode.
