Bartovation pH Test Strips, pH 0-7, 50/Bag

The pH 0-7 test strips include three pads for precise accuracy. They measure in 0.5 pH increments, delivering rapid results within seconds, covering the acid range from pH 0.0 to neutral pH 7.0. When compared to the color chart, ensure the closest match of all three pads for accurate readings. Typically, only one or two pads will change color for any given acid.
