This Hydrion pH Paper provides excellent color separation in both the acidic range (below pH 7) and the alkaline range (above pH 7). Commonly used to test urine and saliva, it offers an easy to read, single color match at every .2 to .3 interval from pH 5.5-8.0. Try always to test urine, as saliva can often give false readings since it is easily influenced by recent food or drink consumed.
The color chart has pH Paper 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. Simply tear off a small strip of pH paper, dip into the test solution, then instantly compare the resulting color with the matching pH Paper color chart.
