OxyFerm Dissolved Oxygen Sensors
The OxyFerm FDA is an electrochemical dissolved oxygen sensor suited for applications with high demands for hygiene, e.g. in pharmaceutical industry, in biotechnology and in food & beverage production. It is available with 12 mm or 25 mm shaft (XL) diameter. When using Oxylyte USD electrolyte, even upside-down insertion is possible. The sensor is equipped with a FDA approved membrane for usage in hygienic processes. It can withstand steam sterilization, autoclavation and CIP cleanings. The OxyFerm CIP with its special designed membrane cap is designed to withstand frequent and harsh CIP cleanings.

Does carbon dioxide sparging impact my DO measurement?
-
Does salinity impact my DO measurement?
Yes, salinity of a solution generally has an inverse relationship to the dissolved oxygen content within the solution. Arc sensors can have the salinity value of the liquid added in to correct the measurement by using ArcAir. -
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.
