pH Controller

The pH controller detects the concentration of hydrogen ions in a solution through an electrode and converts the pH value into an electrical signal for display. It is used for monitoring and adjusting the acidity or alkalinity of liquids and is commonly applied in water treatment, chemical reactions, and wastewater management processes.
Selection
When selecting, consider the measurement range covering the usage requirements, electrode material adapting to the characteristics of the measured liquid, temperature compensation matching the working conditions, protection level meeting the installation conditions, and calibration methods ensuring maintenance convenience.
