Note:
This paper does not apply to buffer liquids and very weak acid-base solution concentrations lower than 0.01%.
Store in a cool dry place away from direct sunlight.
Description:
1. Apply the test liquid on the PH test paper and read PH in 30 minutes compared to the color chart in the package.
2. The number next to the chart color is pH. The pH scale ranges from 1 (very acidic) to 14 (very base) and 7 is neutral.
