Although the glass electrode, first mentioned in the literature over 100 years ago, is still the preferred analytical tool for determining hydrogen ion activity in aqueous media, there are a number of applications for other sensors that also measure pH. Even if they do not correspond to the measuring performance of the glass electrode in terms of, e.g., accuracy, reproducibility, and long-term stability, they open up the feasibility of using electrochemical sensors even where the operation with glass electrodes is not possible. This applies in particular to scenarios in which extreme and harsh environmental conditions prevail. Currently relevant here are, for example, measurements in geothermal plants or directly on arable land in agricultural production. In the present article, new electrochemical devices based on antimony electrodes are presented especially for these purposes; in addition, the use of the antimony electrode as a basic electrode for the CO₂ determination according to the Severinghaus principle is reported on.

尽管玻璃电极是100多年前在文献中首先提到的，但它仍然是确定水性介质中氢离子活度的首选分析工具，但其他用于测量pH值的传感器也有许多应用。即使它们在例如准确性，可重复性和长期稳定性方面不符合玻璃电极的测量性能，即使在无法使用玻璃电极操作的情况下，它们也开辟了使用电化学传感器的可行性。这尤其适用于极端和恶劣环境条件占主导的情况。目前在这里相关的是，例如，在地热工厂或直接在农业生产中的耕地上进行的测量。在本文中，为此，提出了一种新的基于锑电极的电化学装置。另外，使用锑电极作为CO的碱性电极₂报告了根据Severinghaus原理进行的确定。
