Online pH Monitor

Online pH meters measure the potential difference generated by the concentration of hydrogen ions in a solution through electrodes, which is then converted into a pH value by a transmitter. They are used for continuous monitoring of changes in the acidity or alkalinity of liquids and are commonly applied in water treatment and chemical reaction process control.
Selection
When selecting, consider that the electrode material should be compatible with the corrosiveness of the medium, temperature compensation should match the process range, the protection rating should meet the installation environment, the output signal should be compatible with the control system, and the calibration method should align with the maintenance cycle.
