A sensor for monitoring the amount of crevice corrosion which may be taking place in water systems, for example HVAC systems, or be used in refineries or chemical processing facilities, comprises one or more metal wires 2 wrapped around threads or grooves 1 in a non-conducting body 3. The grooves form natural crevices which replicate crevices within real systems. The sensor is inserted into a water system pipe for example and the electrical resistance of the wire is monitored over time to indicate corrosion. The sensor output may provide an easily read user interface or may be captured by a data logger for remote monitoring. |
