pH Calibration

1. A pH calibration is the procedure of adjusting the pH meter by measuring solutions of known pH values. The characteristic of a pH electrode will change with time due to electrode coating and aging. And even a pH electrode would be stable over time, pH electrodes cannot be produced with identical characteristics.
2. In practice the response of a real pH sensor does not exactly follow the Nernst equation. This difference between the theoretical and actual behavior of a pH electrode must be compensated for. A calibration is required to match the pH meter to the current characteristics of the used pH sensor.

Tips: How does the pH electrode work?

1. A pH electrode is a sensor that measures the concentration of hydrogen ions (H+) in a liquid. A pH electrode consists of glass and a reference electrode. The glass electrode contains ionized glass with high resistivity, which is in contact with the liquid.
2. The hydrogen ions in the liquid react with the alkaline substance on the glass, creating a potential difference. The reference electrode is relatively unchanged as a reference standard for comparing potentials.
3. The pH value is calculated by measuring the potential difference between these two electrodes. As the concentration of hydrogen ions in the liquid increases, the potential difference also increases. The pH electrode can be used to measure the pH of water, beverages, food, soil and other samples.
