phion® pH Stix are unlike most on the market. Due to the narrow range in pH of these bodily fluids (generally 5.8 to 7.6) it is imperative that a pH test gives an clear indication in small pH unit increments. Ours do. Our test strips give an indication in .25 pH unit increments, and test a range of 5.5 to 9.0 (5.5, 6.0, 6.25, 6.5, 6.75, 7.0, 7.25, 7.5, 7.75, 8.0, 8.5, 9.0). Plus, pH Stix use the double color indication method, allowing for a more accurate determination of the pH value of what you are testing. |
