pH Paper

pH paper roll

  • Description

This is used for confirmation of completion and quality when activating EM. The range is 2.9 - 5.2 and we're 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.
