The TX-1 measures ambient oxygen levels using the principle of florescence quenching by oxygen. This provides the benefits of lower power requirements and a longer lifespan than typical oxygen sensors.

The TX board combines the sensor with 24VDC operation, robust RS485 Modbus, and 4-20mA industry standard interfaces, and the ability to zero or span calibrate the sensor. it is mounted on a 30 mm PCB to fit industrial applications. The O2 is UV and has zero cross to any gas concentrations.

Combined with the TX board or the Development Kit, the sensor provides accurate oxygen/carbon dioxide 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
