Knowledge popularization of ph meter digital

The working principle of ph meter digital: Most ph meter digital works on the principle of primary battery. The electromotive force between the two electrodes of the primary battery is based on the Nernst law, which is not only related to the properties of the electrode itself, but also to the solution in the solution. concentration of hydrogen ions. There is a corresponding relationship between the electromotive force of the primary battery and the concentration of hydrogen ions, and the negative logarithm of the concentration of hydrogen ions is the pH value.

Fields of application for ph meter digital: ph meter digital applications range from industrial water and waste treatment to flotation processes in mining, including pulp and paper, metal processing, chemicals, petroleum, synthetic rubber production, power plants, pharmaceuticals, food processing, etc. In a wide range of fields, it is also the necessary inspection equipment for QS and HACCP certification in food factories and drinking water factories.
