Acid-Base Test Paper

pH test strips use acid-base indicators that change color at different pH levels to detect the acidity or alkalinity of a solution. They are used for quickly determining the acidity or alkalinity of samples and are suitable for laboratory, educational, and simple on-site testing.
Selection
When selecting pH test strips, it is essential to consider that the measurement range covers the pH value of the sample to be tested, the accuracy meets the testing requirements, the packaging's sealing ensures no moisture or deterioration, and the product's stability guarantees reliable results.
