Carbon monoxide detector
Device that measures carbon monoxide (CO)
Carbon monoxide detector
A carbon monoxide detector or CO detector is a device which detects the presence of carbon monoxide (CO) gas, and is used to prevent carbon monoxide poisoning. Most CO detectors use a sensor with a defined, limited lifespan, and will not work indefinitely. In the late 1990s, Underwriters Laboratories (UL) changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) alarm. This applies to all CO safety alarms that meet the UL 2034 standard; however for passive indicators and system devices that meet UL 2075, UL refers to these as carbon monoxide detectors. CO is a colorless, tasteless, and odorless gas produced by incomplete combustion of carbon-containing materials. It is often referred to as the "silent killer" because it is virtually undetectable by humans. In a study by UL, "Sixty percent of Americans could not identify any potential signs of a CO leak in the home". Elevated levels of CO can be dangerous to humans depending on the amount present...
