PH Electrode Series
The principle of pH electrode measurement is electrochemical method and galvanic battery principle. The primary battery is a system whose function is to turn chemical energy into electrical energy. The voltage of this battery is called electromotive force (EMF) which is made up of 2 half-cells, of which one is called a measuring cell whose potential is related to specific ionic activity; the other is a reference half-cell, commonly known as a reference electrode, which is generally interlinked with the measuring solution and is connected to the measuring instrument. The potential difference produced by the galvanic interaction inside the electrode is transmitted to the pH controller, and the corresponding algorithm is transmitted to display the pH value.Application:
