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.

In industries such as chemical manufacturing, electronics cleaning, metal etching, and semiconductor fabrication, hydrofluoric acid (HF) is a ubiquitous yet highly corrosive medium. Due to its unique chemical properties, standard pH electrodes often have an extremely short lifespan in hydrofluoric acid environments—sometimes failing or sustaining damage within a very short period. Consequently, selecting the appropriate pH electrode based on specific fluoride ion concentrations is critical for ensuring measurement stability and minimizing maintenance costs.
