All Zero-voltage ammeters, including the zero-resistance ammeter or the shunt-resistance ammeter, impose a small voltage between each of the electrodes and the coupling joint. An experiment studied the effect of the voltage imposed on the measured corrosion currents using a CMAS probe. Experimental results.
A technology to detect corrosion damage and estimate extent and location within an enclosed volume. This coating condition monitoring (CCM) system is a network of sensors that measure conditions and electrochemical parameters to evaluate the health of coating and substrate for steel plates and tanks.
