pH Range Test Paper

pH test strips are made by impregnating filter paper with pH indicators. When exposed to a liquid, the indicator changes color according to the hydrogen ion concentration. By comparing the color with a standard color chart, the pH range can be determined. They are used for rapid detection of the acidity or alkalinity of solutions in laboratories and industrial settings, such as water quality monitoring and chemical reaction control.
Selection
When selecting, consider the measurement accuracy requirements. Ordinary test strips are available in either a full range of 1-14 or a more detailed range of 2-9. Pay attention to the color reaction time of the test strip and its compatibility with the color chart. For special samples, choose materials that are corrosion-resistant. When storing, keep them away from light and moisture, and check the expiration date to ensure stability.
