Manufacturer's description: To read a pH strip with a pH range of 0 to 14: 1 to 3 very acidic substances; 4 to 6 acidic substances; 7 neutral substances; 8 to 11 basic substances; 12 to 14 very alkaline substances. What is pH? The pH value (p=potential, h=hydrogen) indicates the acidity or alkalinity of an aqueous solution. The measuring range extends from 1 (very acidic) to 14 (strongly alkaline). Using the provided color chart, you can quickly and reliably determine the pH value of your test liquid. Examples from everyday life: Lemon juice = 2.5, Beer = 4.5, Milk = 6.5, Blood = 7.4, Soap = 8-11, Bleach = 12.5. How to use: Dip the pH test strip into the liquid, place a drop of liquid on the pH paper, or press it against a wet sample such as soil. The color change of the indicator paper should correspond to the color scale on the provided pH chart in approximately 15 seconds. Wide range of applications: The pH test strip can be used to test lemon juice, milk, soap, detergent, etc. It helps you maintain a healthy body.
