pH Detection Meter

A pH meter measures the hydrogen ion concentration in a solution using a glass electrode and a reference electrode, generating a potential difference that is converted into a pH value. It is used to monitor the acidity or alkalinity of liquids and is commonly applied in fields such as water quality analysis, chemical production, and food processing.
Selection
When selecting, consider the measurement range to cover usage needs, accuracy to match testing standards, and electrode materials to suit the characteristics of the measured liquid. Pay attention to temperature compensation functionality, calibration convenience, and instrument stability. Choose between portable or benchtop models based on the usage scenario.
