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
