<p>The reference electrode works with a monitoring unit. Electrical resistance between an output or drain electrode (8) and a first electrical contact (20) is measured. The reference electrolyte (6) is subjected to a pressure above that of the measurement solution (10). In a variant of the design, a first contact (36) is formed by an electrically-conducting coating. This is arranged in a single-rod measurement chain (24), preferably concentric about a measurement electrode (26, 30). A second electrical contact (42) may be included in the interior (4), which only becomes immersed if the reference electrolyte level (18) rises above a given maximum (FM). An independent claim is included for the corresponding method of monitoring a reference electrode.</p> |
