Natural Gas Leak Detector, Plug-in Propane Natural Gas Detector for Home Kitchen RV, Combustible & Explosive Gas Alarm for LPG, LNG, Methane

This is an LEL meter (lower explosive limit) I used LEL meters in industry for years to look for dangerous situations. For $20 this is a really inexpensive item to assure safety in your home. An LEL would also detect a gasoline leak in your garage, or if your propane tank began to leak.I have mixed feelings about it being 120VAC, as it would not work in a power outage; BUT, it has no batteries to discharge and render the unit useless.I also have smoke detectors, a CO (carbon monoxide) meter, as well as these two new LEL meters. Better safe than sorry!!!

My sister is having trouble with her gas stove. The pilot light has gone off at least twice. Her security system doesn't pick up this type of gas leak, only co2. It simply plugs in, but the size takes up space. Upon installation, there are two loud beeps. It appears to be extremely accurate and very sensitive. As the gas clears, you can see the decrease on the meter.

Easy to install. Works well. You can definitely hear this when it goes off.

I had been smelling gas from my stove periodically for years. My super (I live in a NYC co-op) would come with their detectors and say "No Leak". After the recent reports of how harmful gas stoves are I decided to buy my own detector on 4/6/25. Today, 4/14/25 the alarm went off! I immediately called the Fire Department and they came and said "No leak "as well since the meter had gone back to zero but they turned off the gas until Con Edison could come check it out. The super comes to check out the stove and this time since the oven was already pulled out, he actually checks the back of the stove and THEN his meter goes bonkers. Turns out the lugnut is loose! I would never have known or been able to prove there was a problem without this device!

I can't recommend this product based on my experience. Plugged it into the kitchen, near our stove and oven. Everything appeared to be working fine for the first couple months. Then, one day, it began beeping nearly every time we baked something. We became worried we had a leak, so we checked every connection for bubbles with soapy water but could not identify the source of any leak. The alarm would usually stop beeping within a minute or two and then go back down to either 0, 1 or 2 and stay there for hours. Then the next time we turned on the oven, the reading would again jump to level 3 or 4 and the beeping would start over for a few minutes.We continued searching for a leak and couldn't find one. Eventually, the alarm started going off at random times, even when we were sure there could not be any gas in the room. At one point I breathed on it, and the gas reading level jumped to a 6 and the alarm went nuts for several seconds.As a final test, we moved a different gas detector into the kitchen where this one was and moved this one into our utility room, where the other detector had previously been plugged in. The new detector in the kitchen consistently showed 0 and detected no gas. However, this detector now consistently showed levels of gas in the utility room between 2 and 3, with the alarm sounding periodically throughout the day and night. This was odd because the other detector had never beeped once over the several months it had been in the utility room. I checked every gas connection in that room for leaks and eventually had an HVAC company come and do the same. Like me, they couldn't find any. We concluded that this detector is malfunctioning and giving false alarms. Of course, I'm about 2 months past the return window on the product, so it looks like I've simply wasted my money.

Knowing that LPG is heavier than atmospheric air, the gas detector was install in our basement. The alarm sounded immediately showing 3%, the lower end of the explosive range. WOW. Fortunately our basement is not finished allowing access to all of the gas piping. Using soapy water to check all of the fitting, one fitting was found leaking and was easily tightened. After airing out the basement the detector has indicated 0% ever since. Very fortunatere to have found this.

Muy buen producto, justo lo que necesitaba. Cumple con lo que promete, se nota la calidad y ha funcionado sin problemas desde el primer uso. La instalación y uso fue sencillo y el desempeño ha sido excelente. Le hicimos varias pruebas con gas y recciono al mismo. Totalmente satisfecho con esta compra, sin duda lo volvería a elegir. Lo recomiendo sin dudar.
