​This sensor 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 on the Download page.
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.

Works with the following Dataloggers:

VHub4 and VHub8
