Reliable protection against LPG gas leaks with a loud 85dB alarm and live digital gas readout
- Undetected LPG or natural gas leaks in the kitchen
- Not knowing gas concentration levels in the home
- Missing a leak when away or asleep due to no audible warning
Catch a gas leak before it finds you
Stop guessing whether your kitchen is safe. A plug-in detector shows the live gas level and sounds an 85dB alarm when it rises, so you know, even when you are asleep or away.
See the gas level, not just a guess
- A live gas level on the wall
A 3-digit red LED shows the gas concentration as it moves. You see a rise long before the alarm sounds, and you can judge whether the situation is a passing smell or a real leak.
- An 85dB alarm you cannot sleep through
The buzzer is rated at 85dB, loud enough to wake a sleeping household. The alarm point is set at 10 plus or minus 3 percent LEL, so the sound comes when the air is actually moving toward danger.
- Plug in, leave it on
The unit draws 3W from a 100-240V supply and runs permanently with no batteries to swap. Plug it in once beside the hob and it keeps watching.

Choose the wall socket closest to the gas hob or LPG water heater. Plug the 3-pin unit in and leave it there.
- 2Wait for the POWER light
The POWER LED lights when the unit is running. The STATE indicator and the 3-digit display show its current reading.

Press and hold the round test button to confirm the 85dB buzzer and the red ALARM LED work before you rely on it.
A leak does not wait for a good moment

The smell that will not leave
You turn off the hob and open a window, then wonder whether the smell is fading or whether your nose has simply stopped picking it up. Mercaptan additive dulls fast, and a sniff tells you nothing about the level in the room.

What a slow leak does overnight
A loose fitting or a tired valve can release gas slowly for hours. By morning the room can already be at a level that matters, and nobody in the house noticed because everyone was asleep.

A sentry in the socket
The unit plugs into a standard socket beside the hob or water heater and stays there. The display reads the concentration in real time, and the 85dB buzzer sounds when the level crosses its threshold. You stop second-guessing the stove.

Questions and answers
Yes. The packaging lists alarm density points for LPG at 0.1 to 0.5 percent, natural gas at 0.1 to 0.3 percent, and coal gas at 0.1 to 0.5 percent. The display shows the level as it changes.
You plug it in yourself. It uses a 3-pin plug and runs from 100-240V AC, so it fits a standard socket beside the hob or water heater. No drilling, no wiring, no installer.
The alarm triggers at a set concentration threshold of 10 plus or minus 3 percent LEL, and the live readout lets you watch the level before it crosses that point. Keep the unit a sensible distance from the kettle spout and the hob so cooking vapour does not sit directly on the sensor.
Yes. It is built for continuous use and draws 3W, the operating range is -10 to 50 degrees, and humidity is rated up to 95 percent RH without condensation. Leave it plugged in and it keeps monitoring.
Place it on the wall socket nearest the gas hob or LPG water heater. Gas is heavier than air, so keep the unit low on the wall and clear of the buzzer grille, so the sound reaches the room.
A battery sensor needs replacing and often shows no level. This unit costs nothing to run beyond its 3W draw, has no batteries to forget, and shows a live reading you can check any time.
