LuminOx Optical Oxygen SensorLuminOx Optical Oxygen Sensor LuminOx Evaluation Board

The LuminOx family is a range of factory calibrated optical sensors which measure ambient O2 levels 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. 

  • Low Drift
  • RoHS Compliant
  • Extended Temperature Range compared to Electrochemical Sensing Devices
  • Low in Cost
  • Factory Calibrated
  • Measures Temperature & Pressure (If selected)
  • Small & Compact
  • Maintenance Free

LuminOx, unlike other oxygen sensor technologies is stable and robust, it is RoHS compliant as it does not contain lead or any other hazardous materials and has negligible cross sensitivity.  

LuminOx can be purchased as a single optical sensor, or as part of an evaluation kit which includes the LuminOx Sensor coupled with our Evaluation Interface Board, which was designed to allow customers to easily evaluate the sensor with minimum effort or design work.
