Ion-selective electrodes are used in analytical chemistry and biochemical research where accurate measurements of ionic concentration in aqueous solutions are required, taking the guesswork out of water quality testing measurements. Certain models are specially calibrated for detecting and measuring various chemical concentrations in wastewater, drinking water, and general water quality applications. Various different ion-selective membranes are used in ISEs, with most models featuring easy replacement filling solutions and some boasting membrane technology that doesn’t need replacing.
