Achieving cost-effectiveness and efficiency - Simply tear off a small piece of pH test paper and place it on a clean tabletop, then carefully drop a small amount of sample solution onto the center of the pH test paper to promptly observe an immediate color change. Each packet of pH strips is accompanied by a unique standard colorimetric chart that indicates the corresponding pH value for each color. By simply matching the test results to the standard colorimetric chart, one can easily determine the correct pH value. Do not immerse the pH test strip directly into the solution, otherwise the test results will not be trusted. pH test paper is extensively utilized in various production fields such as chemical, food, aquaculture, and agriculture. For instance, pH testing is necessary during the manufacturing process of fertilizers, soaps, cosmetics, and condiments. Additionally, monitoring soil and water pH levels are crucial when planting trees or raising fish. In daily life scenarios like measuring urine or saliva pH levels can help us understand our physical condition.
