Liquid Volumetric Flow Rate: 9.5 to 2800 GPM. Electrical conductivity (EC) refers to a solutions ability to carry an electrical current, measured in microsiemens per centimeter (S/cm). The electrical conductivity of a solution of an electrolyte is measured by determining the resistance of the solution between two flat or cylindrical electrodes separated by a fixed distance. The conductivity probe is inserted into the water, and an electrical current flows between the two electrodes inside, reading the electrical current and providing the conductance value. The CDH-93 resistivity and conductivity meter uses advanced automatic frequency conversion and booster technology to keep the electrode constant the same in different solution strengths. Conductivity ranges tell us a lot about the quality of water because it is a direct measurement of how many pollutants and contaminants are in the water and an indirect measurement of salinity. Conductivity is the electrical current in a solution, but that value depends on the liquid's ionic strength. This value indicates the total dissolved solids. The ability of the substance to conduct or transmit heat, electricity, or sound is known as conductivity. Conductivity ranges are best measured directly using a conductivity probe with a conductivity meter/sensor. These probes have a generally wide range of conductivity so the exact value of the sample does not have to be known. Test everything from ultrapure to ocean water.
