OxyGold G Dissolved Oxygen Sensors
The OxyGold G is an electrochemical dissolved oxygen sensor designed for processes in which very small amounts of oxygen have to be traced, like in the pharmaceutical or microelectronics industry. It is also suitable for processes where high pressures are applied.

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. -
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.

Comparing Optical To Polarographic Dissolved Oxygen Measurement
There is a clear trend in the market towards replacing polarographic with optical dissolved oxygen. When evaluating the switch to optical, engineers must consider if there will be any impact on the current process due to the change in measurement principle. -
