The size of the test strip is 55mm x 9.0mm/2.20x 0.4, and each package is equipped with 160 pieces of measuring paper.
Economically reliable, pH testing range is 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14.
After a few seconds of contact between the solution of the tasting paper and the test paper, a color change will occur. Remove the small test paper strip and compare the test results with the standard color on the cardboard. When the pH value is 7, it is neutral. When the pH value is greater than 7, it is acidic. When the pH value is less than 7, it is alkaline.
The color change of the test strip must match the pH color chart within approximately 15 seconds, and it will perfectly indicate the true acidic or alkaline substance.
Test strips can be used to test water, swimming pools, aquariums, lemon juice, liquid detergents, soil, milk, detergents, saliva, urine, and sweat, helping you maintain an energetic body.
