摘要
Electrochemical probes for corrosion monitoring in an environment that may cause the formation of electron conducting deposits and the method for making such probes were disclosed. The probes have exposed fingered electrodes. Except for the sensing areas at the tip sections, all surfaces of the exposed electrodes are coated with an inner electrically insulating coating or tubing and one or more additional coating(s) or tube(s). One of the additional coatings is ion conducting. The electrodes are spaced such that there are gaps between the outer surfaces of the neighboring electrodes to prevent the formation of a continuously distributed electron conducting deposits between the sensing surface of one electrode and the sensing surfaces of the other electrodes. These probes are especially suitable for applications in gas systems and oil-water mixtures containing hydrogen sulphide (H2S).
