Description

The Hydrion Double Roll pH Papers consist of two rolls of pH papers packaged in a protective plastic dispenser with stainless steel cutoff lips and two matching colour charts. pH colour changes are distinct and easily matched to the colour chart. This Hydrion pH Paper provides excellent colour separation in both the acid range (below pH 7) and the alkali range (above pH 7). It offers an easy to read, single colour match at every .2 to .3 interval from pH 5.5-8.0.

Directions

• Simply tear off a small strip of pH paper, dip into the test solution, then instantly compare the resulting colour with the matching pH colour chart.
• 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.
