PATIKIL PH Test Paper Strips – 12 Rolls, 5 Meters Each, PH 0-14 Full Range, For Water, Soil, Food, Saliva

Need to check pH levels quickly and easily? These pH test strips are super convenient. You get 12 rolls, each 5 meters long (about 16.4 feet), so you've got plenty for tons of tests. They cover the full pH range from 0 to 14, with a clear color chart to match your results. Just tear off a piece, dip it into your sample – whether it's water, soil, saliva, soap, or food – and compare the color change to the chart. The strips are thin (0.2mm) and about 8.5mm wide, made from sensitive litmus paper. Great for science projects, gardening, aquarium maintenance, pool testing, or even checking your body's pH. Store them in a dry place, keep your hands dry when handling, and avoid extreme temperatures for accurate readings. A must-have for hobbyists, teachers, or anyone curious about acidity and alkalinity.
