    AcidiMeter

    Overview Standards Terms
    An acidity detector measures the hydrogen ion concentration in a solution using a glass electrode and a reference electrode, converting the generated potential difference into a pH value. It is used to monitor the acidity or alkalinity of liquids, controlling reaction conditions and product quality in fields such as chemical engineering, environmental protection, and food production.
    Selection
    When selecting, consider measurement accuracy and range to match the characteristics of the sample to be tested. Check the electrode material and corrosion resistance to adapt to the testing environment. Confirm the temperature compensation function to ensure stable readings. Evaluate the calibration method and maintenance costs to align with usage requirements.
