How to Choose a Dedicated pH Electrode for Non-Liquid Sample Measurement

In food processing, laboratory testing, and quality control, pH value is a crucial indicator for determining the acidity, alkalinity, stability, and quality of products. Traditional spherical electrodes are primarily suitable for liquid sample testing, such as beverages, aqueous solutions, and chemical reagents. However, for non-liquid samples like cheese, meat, fruit, and dough, due to their dense structure and uneven water content distribution, ordinary spherical electrodes often struggle to achieve accurate measurements. Therefore, selecting a suitable pH electrode is essential for improving detection efficiency and data accuracy.

How to Choose the Right pH Electrode for Small Samples

In laboratory analysis, biomedical research and development, and scientific testing, pH measurements of trace samples are frequently required. However, when the sample volume is small or the container opening is narrow, conventional pH electrodes often cannot be easily inserted into the container, causing considerable inconvenience to the testing process. Therefore, choosing a suitable miniature pH electrode is crucial for this application scenario.

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.
