Conductivity & Acidity Meter

The conductivity acidity meter indirectly calculates acidity by measuring the electrical conductivity of a solution, utilizing electrodes to detect changes in ion concentration. It is used for water quality monitoring, chemical reaction control, and quickly determining the acid-base state of liquids.
Selection
When selecting, consider the measurement range matching the sample characteristics, the corrosion resistance of the electrode material, and the accuracy of temperature compensation. Pay attention to the convenience of calibration and data output methods to ensure compatibility with the actual usage environment.
