Digital Hardness Calcium Ion Sensor For Drinking Water
>>Overview An electrochemical sensor that utilizes membrane potential to determine the activity or concentration of ions in a solution. When it comes into contact with a solution containing the target ions, a membrane potential directly related to the ion activity is generated at the interface between its sensing membrane and the solution. The ion-selective electrode functions as a half-cell (except for gas-sensing electrodes) and must be combined with an appropriate reference electrode to form a complete electrochemical cell. Under normal conditions, the potentials of the internal and external reference electrodes, as well as the liquid junction potential, remain constant. Any variation in the electromotive force of the cell fully reflects changes in the membrane potential of the ion-selective electrode, enabling its direct use as an indicator electrode for potentiometric measurement of specific ion activity in solutions. Key parameters characterizing the fundamental properties of ion-selective electrodes include selectivity, dynamic measurement range, response speed, accuracy, stability, and lifespan. The sensing membrane of an ion-selective electrode acts as a selectively permeable barrier, demonstrating only relative selectivity towards different ions.
