Reference electrode is mainly used for:

1. Accurately monitor the state of cathodic protection. Potential measurement for sacrificial anode protection.

2, in the applied current cathodic protection system, as an automatic control of the stable signal source, suitable for buried pipelines and underground metal structures cathodic protection engineering.

3, can be buried in the need to monitor and can not enter the position. Such as: large container bottom center location; Inaccessible locations between underground fuel storage and chemical storage tanks; Urban roads under the network, etc. Can be buried in advance during the construction of the project, long-term use.

4. Telemetry signal source for cathodic protection of pipeline.
