Online pH Meter for Chemical Processes

Online pH meters in the chemical industry detect the concentration of hydrogen ions in solutions through electrodes, generating a potential difference that is converted into pH values. They are used for continuous monitoring of the acidity or alkalinity of liquids in chemical processes, commonly applied in scenarios such as wastewater treatment and reactor control.
Selection
When selecting, consider that the electrode material should be compatible with the corrosiveness of the measured medium, the protection rating should match the on-site environment, temperature compensation should cover the process range, the output signal should be compatible with the control system, and regular calibration should be performed to maintain data accuracy.
