After consumption of the anode body 11, water or moisture penetrates into the interior 20 and dissolves the gelatin capsule 34. As a result, the dye 38 is released and colors the water in the interior 20 or also the entire liquid content of the container 25. This latter change in color can then be made perceivable, for example, through a sight glass (not shown) or another display.

  • the metal body 24 extends with its projection 37 far beyond the lower edge 30 of the test space 15 and into the anode body 11. In this embodiment, an anode core is not provided, rather the test space 15 is extended into the anode body 11.
  • the anode body 11 can also consist of an extruded material encapsulated with an iron anode core 12. This can lead to leaks between the materials of the anode core 12 and the anode body 11.
