How to Choose the Right pH Electrode for Deep Container Measurements
In laboratory testing, chemical production, bio-fermentation, and wastewater treatment, pH electrodes are essential tools for measuring the acidity and alkalinity of liquids. However, many users encounter a common problem: the sample container is deep, and electrodes of standard length cannot reach the liquid being measured, affecting the accuracy of the measurement results.

In the water treatment, laboratory analysis, electronics and semiconductor, and pharmaceutical industries, pH measurement of low-conductivity water samples has long been considered a specialized application scenario. For samples such as tap water, rainwater, deionized water, and ultrapure water—which possess low ion content—standard electrodes often suffer from issues such as slow response times, data drift, and insufficient stability during the measurement process. Therefore, selecting a pH electrode specifically designed for low-conductivity environments is critical for enhancing measurement accuracy.
