pH Indicator Paper

Acid-base test paper, by impregnating indicators, changes color when exposed to acids or bases to indicate the pH range. It is used for rapid detection of the acidity or alkalinity of solutions and is commonly found in laboratories, educational settings, and for preliminary screening of water quality.
Selection
When selecting pH test paper, it is essential to consider measurement accuracy, color change range, and stability. Ensure that the test paper matches the pH value of the solution to be tested, pay attention to storage conditions and expiration dates, and guarantee reliable results.
