Can a Carbon Monoxide Detector Detect Carbon Dioxide ...

A carbon monoxide detector cannot detect carbon dioxide. In general, a carbon monoxide detector uses an electrochemical sensor that outputs electric current proportional to the amount of carbon monoxide the chemicals are exposed to. A carbon dioxide detector uses a non-dispersive infrared (NDIR) sensor that measures light in a sample of air.

Carbon Dioxide Detector - PubMed

The measurement of carbon dioxide (CO2) was first developed in the early 1900s; however, it was complex and of limited clinical use. On the most basic level, end-tidal CO2 (ETCO2) detectors are used to measure the exhaled concentration of carbon dioxide. The concentration of exhaled CO2 correlates t …
