pH Test Strips, 2 Rolls of Test Strips, Swimming Pool pH Test Strips Indicator, Full Range 0-14 The pH paper has a full range of pH which can measure the pH value between 0 and 14. It is easy to read and meets various testing needs. Made from high-quality litmus paper, these pH test strips are highly sensitive and provide reliable, accurate pH results. The color comparison chart allows for precise matching and easy interpretation. To use: Take out a small pH strip, dip it into the liquid for 2 seconds, then remove and compare the color change to the printed color chart on the container within seconds. Lightweight and compact coil design makes the strips easy to use and carry. Each roll is 16.4 feet (5 meters) long, with 2 rolls included for a total of 32.8 feet of testing material. Ideal for science education, allowing children to test tap water, saliva, baking soda, and vinegar to learn about acidity and alkalinity through colorful result grids. Also suitable for aquarium water quality, hydroponics, industrial applications, agricultural testing, and more. Understanding pH: pH < 7 indicates acidity, pH = 7 is neutral, and pH > 7 indicates alkalinity. Lower numbers represent stronger acids; higher numbers represent stronger alkaline solutions. Common applications include: - Water quality testing: Slightly alkaline drinking water may support health (pH 6.5–7). - Cosmetic testing: Low-acid cosmetics may be gentler on skin (pH 5–6.5). - Laundry detergent testing: Weakly alkaline detergents may reduce skin irritation (pH 7–8). - Body fluid testing: Urinary and salivary pH levels can indicate general wellness (urine pH 5.0–7.5, saliva pH 6.6–7.5). - Food analysis: Monitoring dietary pH may help maintain acid-base balance. - Amniotic fluid check: Used to detect potential rupture during pregnancy (pH 7.0–7.5). These urine dipsticks and pH paper strips are made from high-quality litmus paper with a detection range of 0–14, delivering fast, accurate, and consistent results. Universal pH test strips suitable for everyday use in homes, laboratories, schools, and outdoor environments. Ideal for testing saliva, drinking water, aquariums, hydroponic systems, food, soil, detergents, soap, and other liquids. Perfect for educational purposes, science experiments, water quality inspection, and routine pH monitoring. Note: Product measurements are manually taken; slight variations may occur. Color differences due to lighting and screen settings are normal. Actual product appearance may vary slightly.
