Online Digital pH Meter

The online digital pH meter detects the hydrogen ion concentration in a solution through a glass electrode, converting the potential difference into a digital display. It is used for continuous monitoring of liquid acidity or alkalinity, commonly applied in water treatment and chemical reaction process control.
Selection
When selecting, consider that the measurement range covers the usage scenarios, the electrode material is compatible with the measured medium, the protection rating matches the installation environment, the output signal is compatible with the control system, and regular calibration ensures data accuracy.
