Hydrogen conductivity testing in water is an important method used to assess the quality of water and is primarily used to measure the concentration of ions in aqueous solutions.Hydrogen conductivity is the conductivity of water after treatment with hydrogen-based ion exchange resin, which can effectively remove cations (such as sodium, calcium, magnesium, etc.) from water.and replacing them with hydrogen ions, thus reflecting more accurately the content of anions (e.g. chloride ions, sulphate ions, etc.) in the water, which is particularly important for monitoring water purity.
