PH 4,5-10 TEST STRIP (100 TESTS)
The pH value describes the acidity or alkalinity (basicity) of drinking water and is measured on a scale with values between 0 and 14 pH:
low pH values (less than 6) indicate that the water is acidic;
pH values close to 7 indicate that the water is neutral;
high pH values (greater than 10) indicate that the water is alkaline (basic).
According to the Italian Legislative Decree n. 31, 2001, the drinking water pH should be between 6.5 and 9.5 pH. The pH values different from neutrality are due to the chemical elements present in the water. Lower or higher values indicate that the water is polluted by strong bases or acids. Values of pH higher than the pH value of 11 pH or lower pH 4 are to be considered dangerous for the human health.
