How corrosion effect on electrical resistance

WebTo measure the electrical resistivity of the concrete a current is applied to the two outer probes and the potential difference is measured between the two inner probes. Empirical tests have arrived at the following threshold values which can be used to determine the likelihood of corrosion. • When ρ ≥ 120 Ω-m. WebElectrical resistance monitoring involves the use of ER probes, which can be thought of as “electronic” corrosion coupons. Like coupons, ER probes provide a basic measurement of metal loss, but unlike coupons, the value of metal loss can be measured at any time, as frequently as required, while the probe is in situ and permanently exposed to the process …
