Why monitor the pH of water?
pH measurement is a key step in many water testing and purification processes: ● A change in the pH level of water can alter the behavior of chemicals in the water. ● pH affects product quality and consumer safety. Changes in pH can alter flavor, color, shelf-life, product stability and acidity. ● Inadequate pH of tap water can cause corrosion in the distribution system and can allow harmful heavy metals to leach out. ● Managing industrial water pH environments helps prevent corrosion and damage to equipment. ● In natural environments, pH can affect plants and animals.Basic Principle of pH Electrode
In PH measurement, the used pH electrode is also known as the primary battery. The primary battery is a system, whose role is to transfer chemical energy into electrical energy. The voltage of the battery is called the electromotive force (EMF). This electromotive force (EMF) is composed of two half-batteries. One half-battery is called the measuring electrode, and its potential is related to the specific ion activity; the other half-battery is the reference battery, often called the reference electrode, which is generally interlinked with the measurement solution, and connected to the measuring instrument.
