👉 An indicator fluid is a specialized liquid used in electrochemical sensors to detect and measure the presence of specific ions or molecules in a solution. These fluids contain chemical components that selectively interact with target analytes, causing changes in electrical properties such as conductivity or potential. These changes are then correlated to the concentration of the analyte, allowing for precise and sensitive detection in various applications, including environmental monitoring, medical diagnostics, and industrial process control. The indicator fluid's composition is carefully designed to ensure high selectivity and sensitivity, making it an essential component in electrochemical sensing technologies.
