Description
Standard pH paper cannot accurately measure the pH of some solutions (e.g., tap water, distilled water, deionized water, and other pure water samples) because the concentration of dissolved ions is too low. For these samples, use Lo Ion pH Test Kit (pH 1.0 to 11.0). Materials are sufficient for 60 tests. Kit includes 15-ft roll of paper, test tube with cap, and color chart, all in 1 container.
