Kidde Ultra-Sensitive Carbon Monoxide Detector KN-COU-B | Battery-Powered with Digital Display

Overview

The Kidde Ultra-Sensitive Carbon Monoxide Detector KN-COU-B is designed with households that include pets or family members with health considerations in mind. It continuously samples indoor air and emits a loud 85-decibel alarm if CO is detected, helping you stay aware of your air quality without guesswork.

Enhanced sensing for sensitive environments

Beyond standard thresholds, this model provides a digital display that shows CO levels as low as ten parts per million (PPM). This up-front visibility helps you observe gradual shifts in air quality and respond as needed, rather than reacting after a warning.
