The Half Cell Potentiometer is used to measure the half-cell potential of reinforcement steel in concrete (in accordance with ASTM C876) for assessment of corrosion in steel reinforcement.
Typical applications include the following:Condition surveys of suspect reinforced concrete (RC) structures to identify areas with corrosion activity for further analysis (testing for chlorides, depth of carbonation, flaws, or permeation) to establish the cause of the corrosion and estimate remaining service life.
- Monitoring RC structures for changes in corrosion activity.
- Checking the effect of re-alkalization or electrochemical removal of chlorides.
- Measuring the corrosion activity in repaired areas.
