Electrical Conductivity (or Specific Conductance) is the measure of the electrical current carrying capacity of a solution. Ionized dissolved solids in water have the ability to conduct an
electric current. The conductivity of pure water is very low and increases proportionally to the level of contamination present. Accurate conductivity measurement is extremely important in water treatment applications and in environmental evaluations.
Conductivity is also useful as a general measure of water quality. Each water source tends to have a relatively consistent conductivity range that, once established, can be used as a baseline for comparison with regular measurements. Significant changes in conductivity could then be an indicator that a discharge or some other source of pollution has entered a system.
The basic units of measurements are milliSiemens/cm (mS/cm) and microSiemens/cm (µS/cm).
Method of Operation
To operate the Conductivity Meter, switch unit on, remove the electrode cap, immerse the probe into the sample, making sure that the sensor is fully covered. Wait for the readings to stabilize (Automatic Temperature compensation corrects for temperature changes). Take measurement. To clean the probe, simply mix it in tap water.
