Just enough pH paper to sample what our pH test kits have to offer! This card is an easy way to convince a friend or family member that they are what they eat. pH paper is the same 5.5 to 8.0 range as used in the Home Test pH Kit and tests in .2 increments. Includes enough 2" test strips for 15 tests, information on what your pH level should be for optimum balance, a short list of acid and alkaline forming foods, and an overview of what readings should be.
