Smartwares RM400 Gas Detector (5 years)

The Smartwares RM400 Gas Detector warns you in time when it detects butane gas, natural gas, or propane gas. This way, you're aware of a gas leak right away. Mount the detector near your boiler or gas stove, for example. A 85dB signal will sound in the case of a gas detection, which is loud enough to hear throughout the entire house. You connect this gas detector to the power grid, but it uses the included backup battery when the power is down. This way, you know for sure it'll also work if there's no power for a short time. The sensor of the RM400 lasts 5 years. Use the test button to regularly check if the gas detector still works.
