Semi-quantitative test strip

Semi-quantitative test strips utilize chemical reactions to produce color changes, and estimate the concentration of substances by comparing the color intensity with a color chart. They are used for rapid detection of specific components in samples such as water, food, and body fluids, making them suitable for preliminary on-site screening.
Selection
When selecting, consider the compatibility between the detection target and the test strip's detection range, and pay attention to the speed of the color reaction and the clarity of the color gradient. Check the storage conditions and expiration date of the test strip to ensure the packaging is intact. Refer to actual user feedback from commonly used brands in the industry.
