Carbon Dioxide Sensing | CO2 Detector | Carbon Dioxide Sensors

Carbon Dioxide (CO 2) is a colourless and odourless gas, vital to life on Earth, as such carbon dioxide sensing is an important practice. Although difficult to detect, our range of carbon dioxide detectors allow carbon dioxide to be strongly absorbed thanks to our non-dispersive infrared technology in our CO 2 detectors.. Carbon dioxide is mostly nontoxic, unless concentrations become elevated.

CO2 Sensor Calibration: What You Need to Know |

All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number …
