Why can I smell carbon monoxide, but the device isn't detecting anything?
Carbon monoxide is colorless and odorless, so the smell is likely from another gas, such as natural gas. We recommend using a combustible gas detector to find the source.
Why carbon monoxide cannot be detected even when there is a source of combustion?
Not all combustion generates enough carbon monoxide to trigger the detector. CO is produced only during incomplete combustion, and in well-ventilated areas or with complete burning, levels may be too low for detection.
