Hydrion 1-12 pH Test Strips

These Hydrion paper strips cover a full range of pH units from very acidic (pH=1) to very basic (pH=12). The color matching chart affixed to the side of the vial provides an easy reference to identify the pH. These strips provide accurate, immediate and reproducible results, and are a good alternative for the limited acid/base results that traditional litmus paper provides. 100 paper strips per vial, 2" x 1/4" each.
