    The TX Oxygen Sensor with Transmitter is designed for industrial applications where RS-485, 4-20mA and 6-24VDC is required.

    The TX sensor board uses 0-25% oxygen sensor mounted on a TX board that adds a robust RS485 Modbus RTU interface, industry-standard 4-20mA analog output, 6-24VDC power, and is mounted on a 30mm PCB for industrial applications.

    The TX Sensor Development Kits adds a USB to PC interface, a wall adapter and our free GasLab® software for rapid application prototyping, real-time data graphing, data logging, and the ability to zero and span calibrate the sensor. 


    • Oxygen sensors has Low Drift & Cross-sensitivity
    • Serial UART, RS485, Modbus and analog outputs
    • Pressure and Temperature sensors built-in
    • Built to reliably measure gas levels in harsh environments
    • Easy Integration, compact and wide range of power options 


    TX-1 Sensor with TX Board– for integration into industrial applications.

    TX-11 Sensor Development Kit – Adds a USB interface and free Windows software for rapid development, prototyping, sensor testing or scientific projects. Includes 6VDC power supply.

      System Requirements

      • Windows XP SP2 or newer
      • Microsoft .Net 3.5 Runtime Libraries

      Tube cap adapters easily convert 20mm standard gas sensors from diffusion to sampling sensors. Molded polymer grips sensor for easy fit and removal while maintaining a good seal.

      Micro-Pump Kit includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system.

      Nafion tubing is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.

      Micro gas sampling pumps provide a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.
