    Laboratory CouloMeter

    Overview Standards
    The laboratory coulometer measures electrical charge through electrode reactions in an electrolytic cell and calculates the substance content based on Faraday's law. It is used to determine the precise content of components such as metal ions in ink pigments and plastic additives, providing quantitative data for tests like corrosion resistance in coatings and analysis of paper fillers.
    Selection
    When selecting, pay attention to the corrosion resistance of the electrolytic cell material. The accuracy of electrical quantity measurement must match the sample concentration range. Consider automatic titration functions to reduce operational errors. The electrode type should be compatible with the target detection ions. The stability of the instrument can be judged by the baseline drift value. Ensure the supply of supporting reagents to guarantee the continuity of detection.
