General Info
The Mini Great Dane is used to measure the half-cell potential of uncoated reinforcing steel in concrete (in accordance with ASTM C876) and to measure the electrical resistance of the cover concrete.
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
