1. High sensitivity and fast response: The built-in carbon monoxide detection chip and electrochemical sensor are enough to detect the invisible deadly carbon monoxide in the air and respond quickly in the event of a fire, saving your life for the first time.

2. Carbon Monoxide Alarm: This is a state-of-the-art carbon monoxide alarm designed to provide early warning of the presence of carbon monoxide. It features an electrochemical carbon monoxide sensor, an 85dB horn, a fully functional test switch, and red LED light to indicate DC power or alarm.

3. Alert warning: When a dangerous level of carbon monoxide is detected, the red LED will flash and a loud alarm pattern will sound – 85 dB alarm with LED flashing.

4. Easy to install and widely used: CO detector comes with installation accessories, just need to drill holes in appropriate places; for bedrooms, kitchens, living rooms, and any other areas with fire risk, smoke detectors, and carbon monoxide alarms can be installed device.

5. Ultra-long battery life: Using ultra-low-power single-chip microcomputer + photoelectric principle technology, using ultra-long standby battery for 3 years. The CO detector is powered by a 1.5V AA battery (battery not included), low current consumption, and long standby time.
