The Kidde KN-COPP-3 is another detector of carbon monoxide, that is UL listed. It is an electrical device that plugs in but also has a battery for back-up. So that means that it will still function during a power outage. It also has a digital display for easy reading. There is a button used to reset or test. There is a warning alarm when the battery needs replacing. This unit gained high reviews by Consumer Reports, a huge consumers’ advocate. This model got high ratings for recognizing high and low levels of carbon monoxide. The 9-volt battery is included. This would be a good choice that is affordable.
