Beschreibung
Zusammenfassung:	The invention relates to a probe for electrochemical corrosion measurement on a boiler wall or heat-exchanger wall having a tube-web-tube design, which probe is cylindrical and has a segment to be accommodated in a bore in a web of the boiler wall. A simplified fastening mechanism and passive temperature control are provided by designing the segment as a fastening segment for fastening the probe in the web, wherein the fastening segment is coated with a ceramic layer, which electrically insulates the probe from the boiler wall, and the coated fastening segment has, in a cooled state, a first diameter that is less than the diameter of the boiler wall bore and has, in the installed state after reheating, a second larger diameter in such a way that there is a press fit at least between part of the coated fastening segment and the web bore.
