Elro Blue Line kool monoxide detector 3-pack

With the 3-pack of Elro Blue Line carbon monoxide detectors, you can monitor the carbon monoxide levels in three rooms. If the carbon monoxide level remains high for too long, an alarm will sound. In this case, open the windows and step outside for a moment to ensure your safety. High levels of carbon monoxide can be fatal. The detectors feature a display that allows you to check the carbon monoxide level at any time. This way, you can identify low levels and prevent headaches caused by poor air quality. The detectors themselves indicate when the device's lifespan has expired, so you no longer have to worry about the air quality in your home.
