Conductivity Meters

Conductivity meters use a probe to produce an electrical voltage when placed in a solution. They can then measure the electrolytes in it since conductance means the ability of the solution to conduct electrical current. They also measure the amount of completely dissolved solids in parts per million or milligrams per litre. The process is dependant on the temperature of the water so they are able to give general information rather then precise measurements. A contacting-type conductivity meter consists of two electrodes insulated from each other. The electrode-less type induces an alternating current in a closed loop of solution and measures its magnitude. For field work, pocket and handheld conductivity meters are widely used for their convenience. Other types include the thermocouple probe and the isolated conductivity transmitter. Conductivity meters are widely used in the field of environmental science to check for pollutants and contaminants. They are also capable of evaluating salinity levels, soil samples and pH levels. In aqua-cultural and freshwater systems, they monitor the amount of nutrients and impurities. These meters can test the quality of public water supplied to households when people have concerns. Industries like breweries, which rely on a clean water supply, also utilize conductivity meters.
