This special pH paper is used for confirmation of completion and quality when activating EM. The range is 2.9 5.2 and for Activated EM were looking for an ideal range of 3.2-3.5, and at least below 3.9.
Please note: Due to its narrow range, this pH paper is not suitable for measuring soil pH.
Comes in two sizes – 15 feet, which contains 180 tests when using a one-inch length of paper per test, and 3 feet which yields 36 tests. Either option comes with the colour scale to determine the pH value.
Be sure to store pH paper in a cool dry location and only handle it with dry fingers, as it reacts instantly to moisture.
