Conductivity (or Specific Conductance) is a measure of water's capability to pass electrical current and is directly related to the concentration of ionized dissolved solids in water. The conductivity of pure water is very low and increases proportionally to the level of contamination present. Accurate conductivity measurement is extremely important in industrial water treatment applications. Conductivity water tests are often used in environmental applications.

Total Dissolved Solids (TDS) and salinity concentrations of a water sample are often derived from the conductivity measurement. Although TDS is not considered a primary pollutant, for aesthetic considerations, the National Secondary Drinking Water Standard for TDS is 500 ppm. Water salinity influences the types of organisms that will thrive in a body of water as well as the plants that will grow on land fed by a particular water source.

Method of Operation
The 3-in-1 CTSTestr™ combination meter measures Conductivity, TDS, and Salinity. To operate, switch the meter on, select measurement parameter, and immerse the probe in the sample. After the reading stabilizes, take the measurement. The CTSTestr™ can be used for a wide variety of applications including aquaculture, fresh water aquariums, swimming pools, industrial water treatment and wastewater treatment.
