Carbon monoxide alarm with 10-year battery and digital temperature display detects dangerous carbon monoxide for up to 10 years

Uses an electrochemical carbon monoxide sensor, the most accurate CO detection technology available, to detect the CO you can't see, smell, or taste in the air

A built-in 10-year lithium battery means you need to worry about changing batteries during the lifetime of the alarm

This stylish CO monitor is designed to sit on top of a dresser or tabletop, and features a backlit digital display that clearly shows the ambient temperature, as well as current and peak CO concentrations

An 85-decibel horn sounds if carbon monoxide levels are too high, and a test/silence button silences the alarm and allows you to test its functionality
