Page 12: Measurement Basics
ECO 531 - Dissolved oxygen measuring device Measurement Basics Measurement Basics The oxygen sensor 5.1.1 Explanation The oxygen sensor is an active sensor. It consists of a platinum cathode, a lead anode and potassium hydroxide (KOH) as an electrolyte. If oxygen is present, it is reduced on the platinum cathode and the sensor delivers a signal. - Page 13 ECO 531 - Dissolved oxygen measuring device Measurement Basics Note Protective gloves must be worn when commissioning, filling and servicing the sensor. Design α Filling hole: If the electrode is used at high temperatures or if it has been stored without its protective flask for a longer period of time, some electrolyte will be lost due to evaporation.
