The TX board combines the LuminOX LOX-02 Oxygen sensor with a PCB that offers 24VDC operation, robust RS485 Modbus, a 4-20mA industry standard interface, and the ability to zero and span calibrate the sensor. It is mounted on a 30 mm PCB to fit industrial applications.

The LuminOX LOX-02 Oxygen sensor uses the principle of florescence quenching by oxygen. This provides the benefits of zero cross sensitivity to other gases and a longer lifespan than typical oxygen sensors.

Combined with the TX board or the Development Kit, the sensor provides accurate oxygen measurement with a powerful and easy to use interface for OEM manufacturers.


  • Low drift & cross-sensitivity
  • TX Board allows for easy sensor calibration
  • TX Board adds RS485 Industry-standard Interface and separate UART interface
  • Easy integration; compact & low power
