What purpose does a voltage meter serve in corrosion control?

A voltage meter plays a crucial role in corrosion control, particularly in the context of using reference electrodes to monitor the corrosion potential of buried pipelines and other metallic surfaces. By measuring the voltage between a reference electrode and the pipeline, it helps in determining the effectiveness of cathodic protection systems. Proper installation and use of reference electrodes allow for accurate assessments of the electrochemical potential of the pipeline, which is essential for evaluating the corrosion risk and ensuring that the cathodic protection system is functioning as intended.

Understanding the voltage across the reference electrode provides vital information about whether the protective measures are adequate or if adjustments are needed to improve pipeline integrity and reduce corrosion rates. Therefore, the use of a voltage meter for connecting reference electrodes is essential for effective corrosion monitoring and management.
