Automatic online pH Meter

Automatic online pH meters continuously detect liquid hydrogen ion concentration through immersion electrodes, which sense potential differences and convert them into pH signals. They are used for real-time monitoring of acidity and alkalinity in industrial processes, such as wastewater treatment and chemical reaction control, to avoid delays associated with manual sampling.
Selection
When selecting, consider the medium's temperature and pressure range; for corrosive materials, use acid- and alkali-resistant electrodes. Installation methods include flow-through and immersion types, determined based on pipeline conditions. Check the protection level to suit the on-site environment and ensure the output signal matches the control system. Regular calibration and maintenance are essential to ensure data reliability.
