Online pH and Alkalinity Meter

Online acid-base concentration meters convert the conductivity or pH value of a solution measured by electrodes into acid-base concentration, and are used for continuous monitoring of changes in acid-base liquid concentration in industrial processes. They are commonly employed in settings such as water treatment and chemical production.
Selection
When selecting, consider that the measurement range matches process requirements, the material withstands medium corrosion, the accuracy meets control demands, the installation method adapts to pipeline or tank structure, environmental conditions comply with protection levels, and the output signal is compatible with the control system.
