Hydrion pH test strips cover the full range of pH units. A color change will occur for each pH unit, and a color-matching chart is on the side of the vial. The sharply defined color for each pH unit provides more accuracy than litmus paper.
A low cost vial of pH paper (in strips) that covers the full range of 1 to 12 pH units. A color change will occur for each pH unit, and a color-matching chart is affixed to the side of the vial. Two charts are provided on each vial (1–6 pH and 7–12 pH). 100 strips per vial. Consider this paper as a substitute for traditional litmus paper. Although the cost is approximately three times that of litmus paper, the sharply defined color for each pH unit will provide the student with more accuracy than just acid or base as with litmus paper.
