This electrode is used in combination with the Oxygen Adaptor to form the dual range Oxygen sensor, capable of measuring oxygen levels in air, or dissolved oxygen levels in water.
It is supplied with 2 membrane caps, 60 ml of electrolyte (KCl) and polishing paper for the cathode. Variation in oxygen permeability of the membrane is automatically temperature compensated over the 5 to 45°C range.
The Oxygen sensor (adaptor and electrode combined) requires setting up prior to use - allow at least 30 minutes to polarise, then the sensor can be calibrated easily either for use in air or in water. For details of calibration, see the user manual available from the Resources tab.
Hint: Use a magnetic stirrer when using the oxygen sensor in a beaker of water, to keep the water flowing gently past the sensor.
Note: If using pH, Oxygen and Conductivity sensors in the same solution at the same time, they can interfere with each other's signals. Keep the sensors as far apart as possible, or take readings using one sensor at a time.
