COND-5022 can know the conductivity of water, the unit is μS/cm. Conductivity can be regarded as the sum of dissociable inorganic salts in water, including cations (calcium, magnesium, sodium, potassium, iron, aluminum, etc.) and anions (SO42-, Cl-, NO3-, CO32-, HCO3-). It is also another indicator of metal salt concentration in water.
