    The ExplorIR®-W (formerly known as CozIR Wide Range) is a low power, high performance CO2 sensor that can measure up to 100% CO2 levels.

    It is suitable for measuring high concentrations of CO2 in closed-loop sampling applications or battery operation in portable sampling instruments.

    Based on infrared LED technology and innovative optical designs, the COZIR combines the accuracy of NDIR technology with wide-range CO2 measurement in a flexible package for OEM integration.


    • 0-100% carbon dioxide measurement
    • Durable, low power consumption
    • Integrated into harsh environments, in varying degrees of pressure
    • Industry standard serial communication
    • Simple to install, precalibrated and ready-to-use


    GC-0016 ExplorIR®-W Sensor Only - for integration into high-volume OEM products. Contact us directly for wholesale pricing on large quantities of this sensor.

    CM-0121 Development Kit - Easy to use, simply plug the sensor module into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide, to configure the sensor or for data logging.

    Happy with ExplorIR®-W 100% CO2 Sensor

    The CO2 100% meter works well from the get go. As I use it more and more, I am learning more about it. It will stand +5V power and signal for a while. It is rated for 3V3. I have comparing it to the CO2 Meter 30 at the low end of measurements. Under 1% CO2, it is fairly close to each others reading. When it gets over 25000 ppm, the 100% meter is real stable. Very happy with it.
    When it comes to moisture operations (> 0.028 Kg/m^3 water dissolved in air), I had to put con-formal coating on the board or it shorts out. If it runs with condensation, it will show erratic readings +/- 100% from current reading. This means the top surface of the sensor needs to point down when installed to let water drip off. It is currently working nicely in 88% - 92% RH.

    First purchase, ExplorIR®-W Sensore CO2 100%

    Sensor works like expected, still to try under high co2 concentration. Fast delivery (even under hurricane warnings).


    ExplorIR®-W 100% CO2 Sensor

    Perfect deal

    I love the way they do for me. All the things.


    Used for a week to adjust with the analog output a concentration between 10 to 80% (tracking and recording by means of usb conection). The start-up and operation were very convincing.

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