Working Principle of pH meter:
The working of the pH meter is based on the Nernst equation. Nernst equation derives the relation between the electric voltage with ion concentration. The Nernst equation derived for H+ ion concentration is the basis of pH meter. The working principle of the pH meter is potentiometry. The pH meter consists of glass (also called an indicator electrode) and a reference electrode. The glass electrode consists of a glass membrane, which is sensitive to the hydrogen ion concentration of the test sample solution. And the glass electrode potential varies from sample to sample. The reference electrode is standard and has constant potential. The reference electrode does not respond to the test sample solution. The pH meter measures and compares the potential difference between both glass and reference electrodes.

Using the Nernst equation, the potential difference is used to measure the hydrogen ion concentration indicating the pH of a given solution. Due to the potential difference between the two electrodes, the electron flows and generates a current. This generated current is measured by a voltmeter. The relationship between the potential difference generated current and pH has been derived. The potential difference of 1 pH is 59.16mV at 25° C and hence when there is a difference of one pH unit, there will be a change in voltage by 59.16mV. This relationship is employed in measuring the pH.
