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.

Carbon monoxide - Wikipedia

Carbon monoxide has a computed fractional bond order of , indicating that the "third" bond is important but constitutes somewhat less than a full bond. Thus, in valence bond terms, – C≡O + is the most important structure, while :C=O is non-octet, but has a neutral formal charge on each atom and represents the second most important resonance contributor. Because of the lone pair and divalence …
