This convenient Hydrion pH Paper Dispensers contain two rolls of pH paper: one that has color matches for even pH measurements (2.0, 4.0, 6.0, 8.0, 10.0) and one for odd (1.0, 3.0, 5.0, 7.0, 9.0, 11.0). Simply tear off a small strip of the pH paper, dip in the solution to be tested and compare the resulting color against the pH color chart.
Each carton contains 10 dispensers, each consisting of two 15' rolls of test paper and matching color charts (materials for approximately 200 tests per carton).
