Note:
This paper is not applied to buffer fluids, and it becomes a very weak acid base solution concentration less than 0.01%.
Store in a cool dry place away from sunlight.
Instructions:
1. Take one strip and dip in the solution you want to measure. Strip color changes instantly.
2. Quickly match this color with the color chart in the package and get the pH in 15 seconds. Do not wait or dry the strips.
3. The number next to the color of the graph is pH. pH scale ranges from 1 (very acidic) to 14 (very basical) and 7 is neutral.
