Optical Oxygen Sensors

PST offer a range of factory calibrated optical oxygen sensors which measure trace and ambient oxygen levels using luminescence-based optical technology.

The patented technology allows the range of sensors to produce low power operation, while offering a long lifetime.

The range of LuminOx Optical Oxygen Sensors are completely solid state sensors and contain no lead or liquid electrolytes. They are therefore 100% RoHS compliant. They have virtually no cross sensitivity, allowing the range to be used in applications where other oxygen technologies are unreliable due to the particular mix of gases present.
