You use this electrode to measure the pH value of liquids. This means you can determine whether a liquid is acidic, neutral, or alkaline. Is the electrode suitable for heavily contaminated water? Yes, it is specifically designed for dirty and challenging media such as wastewater or paints. This robust industrial electrode is engineered for the most demanding applications involving high levels of contamination and toxins, as well as oily media. Can I use it to measure high temperatures? Yes, it is suitable for applications up to 130°C and remains stable under these conditions. Does this electrode require a lot of maintenance? No, it features a robust design and requires minimal regular maintenance. Is the measurement reliable in the presence of oil or dirt? Yes, it delivers stable readings even in oily and heavily contaminated media. How long does the electrode last in industrial use? Its heavy-duty construction ensures a significantly extended service life.
