How to Compare Acidity & Alkalinity 1. Check the colors of the top and bottom squares and identify their closest matches on the color chart. 2. Locate the midpoint number between the two corresponding pH values—this will be your final pH reading. 3. If the strip's color does not exactly match any shade on the chart, observe its undertones (e.g., orange hints in yellow, blue hints in green) to determine the closest pH value. Storage & Expiration 1. Unopened: Store in a dry, dark place at 2–30℃ (2–8℃ is preferred); shelf life is 24 months. 2. After Opening: Seal the container tightly, store in a dry, dark place at 2–30℃; valid for 6 months. Notes 1. Optimal color reading time: 15 seconds (a longer or shorter time will affect the accuracy of the reading). 2. Avoid touching the reaction end of the test strip to prevent contamination. 3. After taking the required number of strips, seal the remaining strips in the dark container immediately. 4. For testing: Use colorless or light-colored liquids. For dark-colored liquids: Adsorb the liquid with activated carbon and then dehydrate the adsorbed mixture. For turbid liquids: Allow them to settle, then use the clear supernatant for testing.
