The pH meter works on the principle of a galvanic battery. The electromotive force between the two electrodes of the galvanic battery is based on Nernst's law, which is not only related to the properties of the electrodes, but also related to the concentration of hydrogen ions in the solution. There is a corresponding relationship between the electromotive force of the primary battery and the hydrogen ion concentration, and the negative logarithm of the hydrogen ion concentration is the pH value. The pH meter is a common analytical instrument, which is widely used in agriculture, environmental protection and industry. Soil pH is one of the important basic properties of soil. Factors such as the temperature and ionic strength of the solution to be tested should be considered during the pH measurement. c
