The Universal pH test paper is used to test broad-range solutions from 2.0 to 10.0 in increments of 2.0.
Instructions:
Remove one Universal pH test paper from the vial, being careful not to touch the strip anywhere other than where you grasp it. Dip the test strip into the solution being tested for 1-2 seconds. Remove and compare to the color chart for an approximate pH determination of the aqueous solution (accuracy = +/- 1.0 pH). Do not let strip dry before comparing to the color chart.
