LuminOx Optical Oxygen Sensors

LuminOx optical gaseous oxygen sensors provide significant benefits over electrochemical sensors due to their insensitivity to environmental factors such as pressure and temperature.

The LuminOx family of factory calibrated optical oxygen sensors measure ambient oxygen levels using the principle of fluorescence quenching by oxygen.

The patented technology allows SST to produce a sensor that provides low power operation, while offering a much longer lifetime than electrochemical and galvanic sensors.

LuminOx is a completely solid state sensor and contains no lead or liquid electrolytes. It is therefore 100% RoHS compliant.   It also has virtually no cross sensitivity, allowing it to be used in applications where other technologies are unreliable due to the particular mix of gases present.
