Operational safety is tremendously important when using household gas appliances, but even regular maintenance can't fully protect you from an occasional malfunction and a gas leak. The Honeywell CO (carbon monoxide) alarm is there to find out the problem early and before it can turn into something much worse. The intense 90 dB alarm activates when it detects an abnormally high gas level in the room. The device is installed on the wall. This allows you to place it near the gas appliance , eliminating possible detection delays. The model covers a range of up to 3 m. The device does not require you to purchase a central unit and can work as a standalone. The high-performance Honeywell gas leak detector is a must-have for any home, business, or summer house. The model is a smart gas detector. Communicates with the Android and iOS operating systems.
