Carbon Dioxide Detectors are is important for incubators, breweries, indoor air quality, COVID infection, and biological functionality. CO2 monitors are made up of NDIR sensors that last over 5 years. Exposure to high levels of carbon dioxide can be dangerous. At regular levels (400-1,000 ppm), carbon dioxide is safe. When it gets more concentrated (>5,000 ppm) problems such as CO2 toxicity and oxygen deficiency can occur. See our YouTube Playlist of our Carbon Dioxide Detectors.
