A conductivity meter is a device used to measure the electrical conductivity of a solution, which indicates how well the solution can conduct electricity. This property is important in various fields, including environmental science, agriculture, and water quality testing. Conductivity is influenced by the presence of ions in the solution, making these meters useful for assessing the concentration of salts and other dissolved substances. Typically, conductivity meters consist of two electrodes that are immersed in the solution. When an electrical current passes through the solution, the meter calculates the conductivity based on the current flow. These meters can provide real-time readings, helping users monitor and manage the quality of liquids in different applications.
