Conductivity sensors are devices used to measure the electrical conductivity of a solution, which indicates the concentration of ions present. These sensors work by passing an electrical current through the liquid and measuring how easily the current flows. Higher conductivity usually means a higher concentration of dissolved salts or minerals, making these sensors useful in various applications, including water quality monitoring and industrial processes. These sensors are commonly used in fields such as environmental science, aquaculture, and chemical engineering. They can help assess the health of aquatic ecosystems, control nutrient levels in farming, and ensure proper chemical concentrations in manufacturing processes.
