Instruction:
1. Clean and dry your hands. You can also wear lab glove.
2. Tear off one strip and place it on a dry clean surface like glass, plastic, pottery saucer, etc. Or hold it with your hand.
3. Transfer a drop of liquid to the strip with the glass rod applicator or the plastic dropper. The color will change in 0.5 second.
4. Immediately match the color of the strip against the standard pH scale color chart within 15 seconds to obtain the pH reading.
5. Clean, dry the glass rod/the dropper for the next use. Store the strips in a cool, dry place away from sunlight/moisture.
