Industrial pH Meter

Product Introduction:

Online industrial pH meter is a precision instrument mainly used to detect the pH value of liquids. It uses the working principle of the primary cell to achieve accurate measurement of pH. The electromotive force between the two electrodes of the primary cell is based on the Nernst law, which is related to both the properties of the electrodes themselves and the concentration of hydrogen ions in the solution.

There is a corresponding relationship between the electromotive force of the primary cell and the hydrogen ion concentration. The negative logarithm of the hydrogen ion concentration is the pH value.
