Carbon Monoxide Detector, with Digital Display and Replaceable Battery Operation, CO Detector, with Test Button and LED Status Indicator

The carbon monoxide (CO) detector is equipped with a high-precision electrochemical CO sensor, capable of quickly detecting CO gas leaks. It can be used in kitchens, bedrooms, bathrooms, and other locations.

The digital LCD screen displays the battery status and the carbon monoxide concentration in the air (ppm) in real time and emits an audible alarm when the concentration exceeds the limit.

The carbon monoxide alarm detector has a self-test function that automatically detects hardware failures such as internal circuitry and carbon monoxide sensors during normal standby mode.

It is also equipped with a low battery warning that reminds the user to replace the battery to ensure complete protection and proper operation at all times. Powered by 3 AAA 1.5V batteries (batteries not included), it features low power consumption, smooth operation, a long lifespan, and simple installation; it can be easily mounted on a wall or ceiling in minutes.
