Natural Gas CH4 Leak Detector with 85 dB Alarm and LED

Protect your home from gas leaks with this reliable methane (CH4) detector. The device offers fast detection, a loud 85 dB audible alert, a LED visual alarm, self-diagnostics, and easy function verification with the TEST button. Thanks to the semiconductor sensor with long service life and compliance with EN50194-1:2023, you gain peace of mind for the entire household.

This reliable natural gas (methane, CH4) detector continuously monitors the air in your kitchen, boiler room, or garage. When a hazardous concentration is detected, it triggers an instant 85 dB audible alarm and a red LED signal to warn you in time. Integrated self-diagnostics continuously check the sensor and internal circuits, and a yellow LED indicates any fault.

Installation is quick and intuitive—simply fix the mounting plate to the wall, snap the unit into the holder, and plug it into a 220–240 V AC outlet. The TEST button lets you verify the correct operation of both the audible and visual alarms at any time, giving you confidence the detector will respond in real danger.
