It's the most common and relatively accurate method of measuring the pH and keeping pH balance in daily life such as water, urine, saliva, sweat, beverage, tea, juice, skincare product, lotion, spa, sanitizer, shampoo, etc. This pH test kit consists of 2 X 80 pH strips and 2 extra free 0.2ml dropper. Each strip is made of premium grade litmus paper intended for universal application pH 1-14. 1. Tear off a strip from the pack, dip it into the solution under 1 s or with the dropper dipped a small amount of liquid for more accurate result. 2. Immediately shake off excess and match colored test strip to the chart provided before test strip dries to obtain the pH. 3. The value next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutral. 4. Please note that the strips can not indicate the Acid or alkali solution when its density was lower than 0.01%.
