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 described. The probes have long exposed electrodes. Except for the tip section, all surfaces of the exposed electrodes are coated with a coating or covered with electrically insulating tubing, so that only the tip section has uncovered metal that serves as the active areas of the electrodes. The coating or tubing material is such that the deposits cannot easily form on its surfaces. Because the electrical bridging between the active areas of any two electrodes requires the deposition of an evenly distributed layer of the electron-conducting deposits along the path from one area to the other area, the coated surface reduces the possibility of short-circuiting for the active areas of the electrodes. These probes are especially suitable for applications in systems containing hydrogen sulphide (H2S).
