Hydrion PH Paper

This Hydrion pH Paper provides excellent color separation in both the acid range (below pH 7) and the alkali range (above pH 7). It offers an easy to read, single color match at every .2 to .3 interval from pH 5.5-8.0.

The color chart has pH matches at [5.5][5.8][6.0][6.2][6.4][6.6][6.8][7.0][7.2][7.4][7.6][8.0]

Each roll provides for approximately 100 tests.
