Active Potentiometry for Dissolved Oxygen Monitoring with Platinum Electrodes
Sensors, 2018 Potentiometric oxygen monitoring using platinum as the electrode material was enabled by the combination of conventional potentiometry with active prepolarization protocols, what we call active potentiometry. The obtained logarithmic transfer function is
