Some advantages of using Half Cell Potential to measure concrete corrosion probability are:

• Non-destructive test: Only a ground cable needs to be connected to a rebar, the electrical continuity of the rebar mesh needs to be checked, and the concrete surface needs to be pre-wetted for testing
• Quick and easy: The rod electrode can be used for located inspections, while the one wheel and the four wheel electrode for faster inspections of big areas.
• Early detection: The early stages of corrosion can be detected, allowing for prompt remediation before significant damage occurs.
• Standardized: Half cell potential testing is a standardized method
