ElectRode pH Sensor

The electrode pH meter consists of a measurement system formed by a glass electrode and a reference electrode. The glass electrode membrane reacts with hydrogen ions in the solution to generate a potential difference, while the reference electrode provides a stable potential. This potential difference is then converted and displayed as a pH value. It is used to detect the acidity or alkalinity of solutions and monitor the pH status of liquids in fields such as chemical engineering, environmental protection, and food industry.
Selection
Select the electrode type based on the measurement medium: use glass electrodes for conventional aqueous solutions and open electrodes for viscous liquids. Consider the temperature range to match the sample conditions; heat-resistant electrodes are required for high-temperature media. The electrode interface should correspond to the instrument specifications: spherical glass bulbs are suitable for general measurements, while conical designs facilitate penetration into semi-solids. Electrode maintenance should focus on cleanability and membrane thickness.
