    This UV Flux 25% Oxygen Sensor measures ambient oxygen levels using the principle of florescence quenching by oxygen. This provides the benefits of lower power requirements and a longer lifetime. The UV Flux MX board provides pressure, temperature and humidity compensation, enabling accurate operation over a wide environmental range without the need for additional system components.


    • Low Drift & Cross-sensitivity
    • MX Board includes Barometric Pressure, Temperature and % Relative Humidity Sensors
    • MX Board allows for easy sensor calibration
    • MX Board adds RS485 Industry-standard Interface
    • Easy Integration; Compact & Low Power


    CM-42951 Development Kit  Easy to use, simply plug the MX Board into your PC via USB. Use our free GasLab® software to measure and graph oxygen, barometric pressure, temperature, and % relative humidity. Includes on-board memory for data logging.

    UV Flux 25% Oxygen Smart Sensor

    Looks great had it working right away. Really well priced and will likely buy more.

    Does Exactly What it Should

    Very sensitive meter that "just works" right out of the box. Simple to use, and I expect a long life from it unlike e-chem sensors. Make sure you use 3.3v logic and you'll be streaming ASCII in no time.

    "Easy to install, easy to set up, and easy calibration - just what I was looking for."
