OxyGold G Traditional DO Sensors
OxyGold G traditional dissolved oxygen sensors are well suited for trace level oxygen measurement applications such as boiler feedwater and pure water used in microelectronic rinse. The sensor offers an industry standard VP connector with a traditional nanoamp (nA) current output for connection with most commercially available controllers and transmitters.

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. -
Does carbon dioxide sparging impact my DO measurement?
CO2 sparging will not impact the DO measurement using an optical DO sensor. CO2 can impact traditional polarographic DO sensors over time thus more frequent electrolyte replacement may be needed. -
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.
