Abstract
The paper presents the results of long-term tests of pH-metric potentiometric sensors containing metal oxides in concrete, using the example of manganese oxide. Unfortunately, their long-term effectiveness in natural conditions is not known. These tests showed their poor effectiveness in determining the pH value under variable moisture conditions of concrete. The jumps in the potential of the pH sensors resulting from changes in humidity significantly exceeded the so-called theoretical Nernst response (59.16 mV per pH unit), which disqualifies them from monitoring changes in the pH of liquids in concrete pores in natural conditions.
