NOTE:
This paper does not apply to buffer solutions and very weak acid-base solution concentration lower than 0.01%.
Store in a cool, dry place away from sunlight.

Instructions:
1. Take one strip 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 package to obtain the pH in 15 seconds. 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.
