Description
Gas Leak Detector for Home, Natural Gas Detector, Combustible Gas Detector with Leak Alarm
-
Spots leaks quickly: the sensor picks up combustible gas and alerts you in time to take action, with sound and a flashing light.
-
Warns you fast: responds in as little as 5 seconds, or 2 seconds at higher concentrations.
-
Works where you need it: detects natural gas, propane, methane and other combustible gases at home or at work.
-
Tunes to your space: adjustable sensitivity adapts the detector to different rooms and conditions.
-
Simple enough for anyone to run: the button layout makes setup and daily use straightforward.
A gas leak rarely announces itself — by the time you smell it, it may already be a hazard. This gas leak detector's sensor catches combustible gas early and triggers both a loud sound and a bright light so the warning is impossible to miss. It reacts within 5 seconds for most concentrations and 2 seconds when levels run high, giving you time to act instead of finding out too late.

As a propane detector it also reads methane from 50 to 1000 PPM, plus natural gas, gasoline, alcohol and benzene, so one gas sniffer covers the fuels most homes and workshops actually use. It takes about 30 seconds to warm up after power-on, and adjustable sensitivity lets you dial it in for a kitchen, garage or workshop. It's rated to run in temperatures from 32 to 122°F (0 to 50°C) and humidity from 20 to 80% RH, and stores safely from 10 to 50°C at the same humidity range.
