Carolina® pH Test Paper provides a quick and easy method of indicating the pH of a solution by using a single-color change. Refill includes 3 single-roll dispensers; each reel is 15 ft long. Refill DOES NOT include additional color charts. Store up to 3 years under proper conditions.

Note: Due to the extreme similarity in the colors of pH 13 and pH 14 for this paper, the pH range ends at 13. To accurately test for pH above 12, consider using a pH meter or a more sensitive strip, such as the Carolina® pH Indicator Strips (item #894036).

Not for measuring the pH of natural waters, such as streams, rivers, and lakes. To measure pH in these waters, try our Water Chemistry Test Strip, pH 6 to 9 (item #652729) or, for a wider pH range, our LaMotte® Water Test Kit, pH 3.0 to 10.5 (item #652927).
