1.General description The luminox family (lox) is a range of factory calibrated oxygen sensors which measure ambient oxygen partial pressure (ppo2) levels using the principle of fluorescence quenching by oxygen. By default luminox measures ppo2 (mbar) and temperature (°c). An optional pressure sensor enables luminox to also measure barometric pressure (mbar) and to convert the ppo2 reading to an oxygen concentration (o2%). The sensor benefits from low power operation, traditionally associated with electrochemical sensors, while providing a much longer lifetime due to the non-depleting sensing principle. Luminox is ppo2 and temperature compensated, enabling accurate operation over a wide environmental range without the need for additional system components. Unlike other sensor technologies, luminox is very stable and robust, does not contain lead or any other Hazardous materials and has negligible cross sensitivity to other gases. 2.Cleaning The housing of the sensor can be cleaned using a damp cloth. The sensor should not be immersed in any cleaning media. Full application and technical support can be provided by our knowledgable and highly experienced engineering team if required. 3.Benefits -low power -can also measure o2% & barometric pressure (lox-02) -suitable for battery power use -long life - high accuracy - small & compact - low cost -maintenance free contains no hazardous materials -connects directly to microcontroller - without any additional circuitry. - factory calibrated 4.Applications -oxygen detection -portable equipment - breathing apparatus - inerting - medical -lab equipment - agriculture -incubation -fire prevention - flue gas in condensing boilers
