Y401 Natural Propane Gas Detector, Home Gas Alarm and Monitor, Leak Alarm for LNG, LPG, Methane, Coal Gas Detection in Kitchen, Home, Camper (2, Black)

I was cooking dinner and a friend came over and said she could smell gas. I don’t have a keen sense of smell and I could not smell anything. After checking the gas burners the flame on one had stopped working but the gas was still on. I went on line and ordered my gas detector to be delivered the following day. So happy I can feel safer in my home now.

It was really easy to start using it! Great option for a great price if you want something to detect any gas leak of in your house! I recommended it!

Final update...I've been using the firmware updated replacement a few months now. It works really well.There was only one instance where I unplugged it to adjust to a significant and fast environment change. It reset and all is good!....,...........They gave a full refund and shipped an updated new replacement!There has been a software update to make it not react to rapid temperature and humidity changes. The replacement has been working perfectly now.The seller responded that the issue is due to temperature and humidity changes which cause the reading to "drift". They have updated the software for this gas detector. They sent an updated model to try. They also gave a full refund without my asking..................Problem Solved!The Techamor y401 gave us false readings every day. The problems began when it was only a few weeks old, I ordered it in January. It read a constant 1-3, on occasion and it went up to 4-5 and triggered the alarm! It would sometimes read a 0, but only on occasion. I moved it to many different locations indoors and out, and had the same result. It was so erratic that I couldn't trust it. I unplugged it and ordered a real Gas leak detector like plumbers use in order to verify what was happening.The new gas detector is handheld and extremely sensitive, detecting as little as 50 parts per million! I took the new gas detector around the house, to every gas appliance (and every drain opening in case methane was coming up through the plumbing). I did this repeatedly over a period of days and it never detected a gas leak!!I tested the hand held gas detector with both propane and natural gas. It reacted correctly and once the alarm sounded and I turned off the gas, the meter showed lowering gas levels until it returned to it's baseline. I detected both gases before I could smell them! It never once provided a false reading. But it's not practical for 24/7 monitoring.Then I plugged the Techamor y401 back in, and compared it to the professional gas detector. The Techamor again showed gas when there was none. It's junk. Had I trusted the Techamor and called the fire department when the alarm sounded, it would have been embarrassing, and scared my condo neighbors! And wasted the Fire Department's resources.Without an accurate and sensitive device to compare, I question so many reviews that say it's accurate! How do so many reviewers have a way of knowing. Yes, it did sound the alarm when I tested it with propane and natural gas. However, it went off several times when there was zero gas in the air. It went off when we used the toaster oven! And when I was washing dishes! How can you trust it to do one thing when it doesn't do the other correctly?I prefer a plug in detector that provides a constant readout in order to detect when a gas burner is inadvertently bumped on! Now, I don't know what to trust! I don't know if this is typical for the Techamor y401, or if it's defective.

Packaging was excellent. Manual was perfect, even noted where to place unit. I tested it and the sensitivity was excellent. I purchased four of these units.

Good quality

My water heater exploded after 4 yrs and needed to be replaced under warranty. Warranty for parts only; labor was $1600. I decided I would tackle it myself instead. It wasn't easy but I was able to do it myself. I foolishly decided to save a few bucks by reusing the gas flex line. I could smell a leak as soon as I connected it. A trip to the Home Depot and a new gas line later, no gas smell. Afterwards I decided it would be smart install natural gas and CO2 detectors just to be safe. I installed this Techamor Y401 model detector. I tested it using a lighter, just as they recommend in the instructions. And it really works. Glad I bought this!

Simple and easy to use, nice wide set of detectable gasses, great price.

So, I bought these gas detectors to avoid turning our home into a fiery explosion scene straight out of an action movie. With all the utility mishaps happening in the neighborhood, I figured it was time to add an extra layer of protection – you know, just in case.I put these bad boys to the test with our trusty gas stove, and lo and behold, they did their job – the alarm blared! Feeling pretty confident, I did a victory dance until I realized one tiny detail: the alarm is about as loud as a whisper in a library. Either that, or I've suddenly developed selective deafness.So, if you're looking for a gas detector that'll save your bacon without waking the neighbors, these might just do the trick. Just make sure you have superhero-level hearing or a backup plan involving carrier pigeons.

Its an amazing product, providing extra layer of safety

Très facile à utiliser se programme seul après 10 secondes un petit bip et c’est fait

Buen detector de gas, me gustaría que sonara un poco más fuerte pero realmente cumple con su trabajo de avisar en caso de haber una fuga de gas o haber dejado una llave abierta, ideal para las personas de edad avanzada que suelen dejar la llave abierta la llave de gas.

コンセントに直接取り付けるだけでキャリブレーションがスタートし数分で通常モードになりました。ライターでテストしブザーの音も確認できました。耐久性はこれから・・・

Using this in our sailboat and it is so easy to use.
