Salinity analyzer

This principle is based on the physical properties of electric current, and its simple explanation is that electric current is generated by the movement and transfer of electrons between their respective atoms. In a salt content analyzer, the electrode is the channel for current flow. There is a specialized salt solution inside the electrode, and samples with high or low salt content will cause changes in the salt content in the electrode when in contact with the salt solution. When the electrode is tested with current, it will perceive this difference in salt content and output a corresponding value to represent the salt content in the sample.
