The K33 ICB CO2 sensor is designed to measure up to 30% carbon dioxide in real time in biological or scientific applications where artificially high levels of CO2 are maintained in an enclosed apparatus.

*Please note the sensor diagram referenced in the manual displays an opposite drawing of the actual sensor module itself*


  • Long-life NDIR CO2 Sampling Sensor
  • Easy communication using industry standard I/O
  • Properly configured, can take a sample containing almost 100% humidity

The K33 uses a 4.26 um narrow pass filter which is very selective to CO2. There is little interference or cross sensitivity from NO2 below and CO above that wavelength.


CM-0027 K33 ICB 30% CO2 Sensor Development Kit - Easy to use, simply plug the sensor module into your PC via USB. The Devkit includes a K33 ICB sensor with pre-soldered connectors that provide power and connectivity. Use it for evaluation, rapid application development or for experiments. Uses our free GasLab® software to measure and graph carbon dioxide, to configure the sensor or for data logging.
