Instructions: 1. Take one strip from the pack and dip it into the solution you would like to measure. The color of your strip will change immediately. 2. Quickly match this color against the color chart on the inside of your pack to obtain the pH. Do not wait or let the strip dry! 3. The number next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutral. Please note that solutions with a pH of ~5.5 will result in a yellow colored test strip that resembles the original color of the dry strip. Store in a cool, dry place away from sunlight.
