Composite pH Meter

A composite pH meter measures the hydrogen ion concentration in a solution by combining a glass electrode and a reference electrode, generating a potential difference that is converted into a pH value. It is used to detect the acidity or alkalinity of liquids and is widely applied in chemical engineering, environmental protection, and water quality monitoring.
Selection
Select electrode materials based on the measurement medium, considering temperature range and accuracy requirements, and match the instrument's protection rating. Review calibration methods and maintenance cycles to ensure compatibility with the chemical properties of the solution being measured.
