Oxysens Dissolved Oxygen Sensors
The Oxysens is an electrochemical oxygen sensor designed for applications in water, e.g. wastewater treatment, swimming pools or fish farms. It is easy to maintain, because the membrane and the electrolyte do not need to be replaced.
The response time of the Oxysens is fast, it is almost independent to flow and insensitive to soiling.

Does temperature impact my oxygen measurement?
Yes, in a closed system, gas phase temperature is directly proportional to pressure and therefore measured oxygen content. In solution, temperature is inversely proportional to dissolved oxygen content. -
When should I calibrate my DO sensor?
The frequency of calibration will depend upon the duration of process runs and the accuracy required for process control. In bioreactor applications calibration can be performed before sterilization; however many customers choose to calibrate after sterilization as well. -
When should I replace the membrane and electrolyte in my polarographic DO sensor?
The frequency of membrane and electrolyte replacement is process specific and will vary. Routine calibration before each run can identify a high nA current at the nitrogen zero point or low nA current in air, indicating a need to replace the membrane and electrolyte.
