Overview
An electrochemical sensor inside this Kidde detector measures carbon monoxide and shows the level on a digital screen. A sealed lithium battery powers it for life, so it can hang on a wall or sit on a table and travel with you.
Seeing the CO reading and the peak memory helps spot low, recurring leaks before they become emergencies. It is a CO-only device, so it does not replace smoke alarms.
Who it's for
Homes with furnaces, gas stoves or attached garages, and travelers who want a portable CO check. Anyone needing smoke detection should pair it with a separate smoke alarm.
Pros and cons
- Shows actual CO level
- Peak memory catches past events
- Sealed battery, no wiring
- Wall or tabletop use
- CO only, no smoke sensing
- Whole unit replaced at end of life
Performance notes
The electrochemical cell produces a signal in proportion to carbon monoxide, which is how the display shows a level. Peak memory stores the highest recent reading, useful for spotting leaks that happen while you are away.
