The actual water quality testing of drinking water includes the following contents:

(1) pH value: the relevant content of the actual water quality testing of drinking water, including the pH value of the water quality. The pH value shows the acid-base equilibrium state of each soluble compound in a solution. The pH value can affect other water quality standards. When the pH value is less than 7, there will be a pungent odor: when the pH value increases, the water will have a bitter taste and the color will also change.

(2) Conductivity: the relevant content of the actual water quality testing of drinking water, followed by the conductivity of the water quality. Conductivity is a kind of numerical representation of the actual current that the solution conducts

It is a comprehensive index related to inorganic pollution in water. A part of harmful substances will exist in the form of ions after being integrated into the water body, and the measurement of conductivity does not require other chemicals, and the fluctuation range is small. In addition, the conductivity has an obvious indicator effect on the sudden increase of substances in a part of the water.
