Size of paper: 45mm x 7mm (length x width), Includes 3 packs (240 pH strips) and 1 storage case.
The color change of the test strip must be compared to the pH scale color chart within approximately 15 seconds. Different pH levels will result in different color changes. A smaller number indicates greater acidity, while a larger number indicates greater alkalinity.
The body's internal pH levels are closely linked to overall health, and pH paper can help you monitor it by testing various common substances, such as soap, lemon juice, milk, liquid detergent, soil, saliva, urine, and sweat.
