CO Detective 1: CO71A - Monitors, records, and alerts you to the presence of dangerous carbon monoxide in ambient air. The visual display constantly indicates precise quantities while the audible and visual alarms respond to various threshold levels.

Carbon Monoxide (CO) - is a lethal poison produced when certain fuels are burned. It can rapidly accumulate even in areas that might appear well ventilated. Because CO is colorless, tasteless, odorless and non-irritating, it can overcome an exposed person without warning. Recognizing early warning signs of CO poisoning is sometimes difficult because early symptoms of CO exposure (headache, dizziness, nausea) are nonspecific and may be mistaken for symptoms of other illnesses and frequently produce weakness and confusion depriving a person of the ability to seek safety.
