What Is The Best Carbon Monoxide Monitor

A carbon monoxide detector is a device that detects the presence of carbon monoxide (CO) in a building. Carbon monoxide is a colorless, odorless, poisonous gas that can cause death by suffocation. The best carbon monoxide detectors are those that meet the requirements of the relevant safety standard, such as the United States National Fire Protection Association (NFPA) Standard 720. Such detectors typically contain a battery-powered alarm and a sensor to measure CO levels. When the CO level reaches a certain point, the alarm sounds.
