Conductivity Testers
GAO’s water conductivity testers are devices that are used to measure the electrical conductivity of water. Conductivity is a measure of how well a solution can conduct electricity, and in water, this property is determined by the concentration of dissolved ions, such as salts and minerals. The meter may be a simple handheld device or a more advanced instrument with features such as automatic temperature compensation, data logging, and multiple ranges of measurement. High levels of conductivity in water can indicate the presence of dissolved salts and minerals which may be harmful to aquatic life or may affect the taste and quality of drinking water.

GAO’s water conductivity testers are composed of electrodes, circuitry, display, power source, calibration solutions, meter, and carrying case.

The other common names of conductivity testers are conductivity meters, electrical conductivity analyzers, conductance meters, salinity testers, total dissolved solids meters, electrolyte conductivity testers, ion concentration analyzers, cell constant meters, dissolved ion concentration meters, electrical conductance probes, solution conductivity sensors, ionic strength meters, electrolyte concentration analyzers, conductivity measurement instruments and specific conductance meters.
