This Hydrion pH Paper provides excellent colour separation in both the acid range (below pH 7) and the alkali range (above pH 7). Commonly used to test urine and saliva, it offers an easy to read, single colour match at every .2 to .3 interval from pH 5.5-8.0.
The colour 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.
Product Directions:
