Conductivity, Salinity


Description: Conductivity cell electrodes are electrodes that measure the resistance of a sample often using four electrodes. An altering current is passed between a pair of electrodes, while the other two electrodes measure the potential that develops in the solution. The current and potential are used to calculate resistance, which is used to assume the conductivity. Salinity is not measured directly but can be calculated using the resistance and temperature compensation. Conductivity sensors are reliable, accurate, and durable but are susceptible to fouling from aquatic organisms and sediment.
