Qoltec Certified 2in1 natural gas and carbon monoxide (CO) leak detector CH4 CO NG Tuya Wi-Fi 85dB alarm LED

Immediate danger warning – dual detection and alarm system
Early detection of natural gas (CH4 – methane) leaks
The sensor continuously monitors the presence of natural gas (CH4 – methane) in the room. If a leak is detected from the gas installation, cooker or gas boiler, the device reacts immediately, warning of a potential explosion risk. When the safe concentration level is exceeded, a loud 85 dB audible alarm and LED light signal are activated to alert household members of the danger and allow them to take appropriate action quickly.
Carbon monoxide (CO) protection
The detector is also equipped with a carbon monoxide (CO) sensor – a colourless and odourless gas produced during the improper combustion of fuels in stoves, fireplaces or boilers. Thanks to Wi-Fi connectivity and integration with the Tuya Smart / Smart Life app, you will receive an instant notification on your smartphone.

Double warning: 85 dB alarm + notification in the Tuya app

Technology that protects your loved ones
Safety for children and the elderly
Natural gas (CH4) and carbon monoxide (CO) are particularly dangerous for children, the elderly and people with compromised immune systems, as even small concentrations can quickly lead to poisoning. By continuously monitoring the air, the sensor detects the danger at an early stage and immediately triggers a loud 85 dB alarm and LED signal, warning household members of the danger. In addition, a notification in the mobile application allows you to react quickly and ensure the safety of your loved ones.
