NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR ...

Our CO2 sensors do not consume carbon dioxide during the ...

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 nondispersive infrared technology in our CO 2 detectors.. Carbon dioxide is mostly nontoxic, unless concentrations become elevated.
