optical oxygen sensor O2 Gas sensor LOX-02 Description The LuminOx Family is a range of factory calibrated optical sensors which measure ambient O2levels using the principle of fluorescence quenching by oxygen. Our unique patented process allows us to produce an oxygen sensor that benefits from low power, traditionally associated with electrochemical sensing devices, while providing a much longer lifetime due to the non-depleting sensing principle. Applications Typical applications for the Cheap Price Oxygen Sensor LOX-02 are; Oxygen detection Portable equipment Breathing apparatus Inerting Medical Lab equipment Agriculture Incubation Fore prevention Flue gas in condensing boilers
