Potential pH Meter

A pH meter forms a galvanic cell using a glass electrode and a reference electrode to measure the potential difference generated by the concentration of hydrogen ions in a solution. This potential difference is then converted by the circuit to display the pH value. It is used to detect the acidity or alkalinity of liquids, and is applied in fields such as chemical engineering, environmental protection, and food production to monitor reaction processes and water quality.
Selection
Select electrode material based on the measurement medium: use corrosion-resistant electrodes for strong acids and bases, and open electrodes for viscous liquids. Consider accuracy requirements: choose 0.1 accuracy for routine testing and 0.01 accuracy for research purposes. Check the temperature compensation function to ensure it matches the sample temperature range. Confirm the electrode maintenance method: gel electrodes are maintenance-free, while refillable electrodes require regular replenishment of electrolyte solution.
