Our unique technology combines the platinum electrode and the Ag/AgCl replaceable junction electrode to offer a superior platinum combination electrode. This electrode is capable of quick response to oxidation-reduction potentials. The Redox combination electrode measures the ionic strength (concentration) of ions from potentiometric titration techniques. The reference element incorporates a unique silver ion barrier that prevents silver contamination of samples and eliminates junction blockage due to AgCl precipitation. In addition, the replaceable junction feature increases electrode life and stability.
