Online Conductivity Sensor Features
Widely used in surface water monitoring, industrial wastewater and municipal wastewater monitoring, water treatment industry, boiler backwater monitoring, deionization process monitoring, reverse osmosis monitoring, sea water, brine, aquaculture water monitoring, etc.
Conductivity is a measure of dielectric conductivity, the unit is usually expressed in μS/cm or mS/cm，the conductivity of pure water is less than 0.05 S/cm at room temperature，the conductivity of natural water or surface water is 100-1000 S/cm, the conductivity of acid base solution is up to 1000mS/cm.
Two coaxial electrodes are placed in the sample solution, a sine wave voltage is applied between the electrodes and the current value is measured, calculate the conductivity value G or the resistance value R based on the Ohm’s law, the conductivity is determined by the electrode constant K associated with the structure.
