Product description:

Universal pH indicator paper is used to check the pH of soil, water, urine, saliva, aquariums, and for laboratory use. Quickly test the pH of any aqueous solution. The measuring paper comes with a separate color scale from 1 to 14 for direct comparison of results.

• 1-3 indicates a very acidic substance
• 4-6 indicates an acidic substance
• 7 indicates neutral
• 8-11 indicates alkaline
• 12-14 indicates a very high level of alkalinity.

How to use:

1. Soil pH testing

• Put about 1 tablespoon of soil into a clean cup or bowl.
• Slowly add distilled water until the soil reaches a pasty state, stir well with a spoon. The amount of water may vary depending on the soil type.
• Let the mixture sit for about 1 hour; if the soil becomes dry, add a little more distilled water. Dip the pH test strip into the soil sample for about 20 seconds, then remove it and rinse gently with distilled water.
• Compare the color of the test strip with the included color chart to determine the pH value.

2. Solution pH testing (water, urine, saliva, laboratory solutions, …)

• Dip the test strip directly into the solution to be tested.
• Remove the strip immediately and compare the color with the standard color chart to determine the pH.

Note:

• To ensure accuracy, limit the test paper's exposure to air or sunlight for long periods. Store in a dry place, avoid moisture.
• The test paper cannot determine acid or base solutions with a concentration lower than 0.01%.
