Gas Leak Detector – Portable Natural Gas Sniffer for Propane, Methane, LPG, LNG, Fuel & Sewer Gas – Combustible Gas Detector with 12" Flexible Probe for Home, RV, Industrial Use

Package arrived on date given.Read the instructions and set out to what I thought might be a problem.Off the chart. Gas leak on my hot water heater. Union valve or whatever that thing is called. Did what needed to be done and no gas leak.Don't wait for the nausea, extreme fatigue, head crushing headaches and much worse. Every home should have one.I ordered two more to give as gifts.

Works as described. Like the bending neck feature to get around tanks and oven areas. It will be a great asset when running a propane powered generator. Highly recommended for outdoor folk who like to easily check for propane leaks.

They mean it when they say in the instructions to calibrate it outside in clean air. Dial up till it beeps. Then dial down till it’s done beeline and starts clicking. Clicking means it’s sniffing.I recommend rechargeable batteries. They give a constant voltage till they’re dry which helps with consistent detection. Regular alkaline batteries will lose power and seemed like the detection was weaker when the batteries got weak. Both battery types will lose charge fast.It’s very sensitive. It gave a small hit on the pipe dope in connections (stops clicking but no alarm, a warning light flickers off and on). When it found a real leak it let me know with alarm and lights. It detected propane (object of my search) and methane (a surprise coming from a door drain).Glad I have it.

Works perfectly if you read how to use this device. I was able to detect sewer gas with no issues.

works great very sensitive

After multiple failures of various detectors installed in my camper, I opted for this portable device with a much needed sensitivity control. Although this is a battery operated portable device, I installed a 5-volt USB power supply where my previous detectors were installed and added a USB power cord to the unit. I adhered the unit to my camper wall with a velcro strip. Now I have the safety monitoring needed for the camper, and if I need to use the unit elsewhere, I simply detach it and install (3) AAA batteries and it's ready to go. The previous sensors were far too sensitive, resulting in annoying false alarms and they had high failure rates. I couldn't even put on after-shave lotion without setting them off -- ridiculous and very annoying! The sensitivity control on this Y201 is terrific, allowing you to stop the false alarms. ANY detector should be tested weekly, but instead of a test button, why not use the real thing -- I test the unit once a week with a BIC lighter. Also, the camper manufacturer installs the detectors at the floor level, where they can pick up dirt and dust, setting off the unit and possibly even clogging the sensor or eventually disabling it. LP gas is heavier than air and will stay by the floor, but there is no real reason to put the sensor that low to the floor. With the Y201, you can point the sensor down, where it will not have the tendency to pick up dirt or dust, and it will be at a more desirable level from the floor, about 5 or 6 inches. Also, because LP gas is detected by odor, the only time you really need a detector is when you are sleeping! Please note that this unit has an audible feedback feature that indicates proper functioning -- it makes a ticking sound. If you are a light sleeper, the ticking sound may bother you, so keep that in mind. I got used to the sound and it does not bother me at all, and I am a light sleeper. It's like a clock with a second hand, although it is slightly faster than that. Anytime the detector is not needed, it can simply be switched off, and this will also prolong the life of the unit. If you are forgetful and cannot remember to make sure the unit is on when needed, then this may not be for you. If you have small children (or cats) around that could possibly mess with the controls, then this may not be for you. As for me, I am very pleased with the unit and happy that such a device was available. I have been using it for a couple of months now, and I will revise this review accordingly if problems develop. The company now offers a lifetime warranty for the unit, which is amazing since all LP sensors have a limited lifetime, similar to an incandescent light bulb.

It is very easy to use.

I've read all the reviews, like you should too. I won't repeat a lot of what has already been mentioned.I bought this to help detect and sniff out tiny gas leaks in my 70 year old house. These were leaks that I basically could not smell with the exception of that 'every once in awhile' picking up the faint smell of gas whiff in the air of the basement. So far, all of my detected leaks have come from pipe threads that have dried out and have sprung these tiny leaks. In retrospect, bubbles could not find any of them... and I got a sense that many were lingering for possibly decades. Some exist around the old style shut off valves where the stem packing dries out.This device is very sensitive and only needs to be around the leak for a few moments. It accurately and quickly has pinpointed these problems and is almost too sensitive to a fault. While it also detects sewer gas, which will pool in a low spot, gas tends to float on the air and gravitate upward. I'm unsure as to how the 'smell' added (mercaptan) adds molecular weight thus sending the gas lower in the room. Regardless, the sensitivity of this device is five stars.What desperately needs fixing is the calibration wheel, which when zeroed in fresh air is already spun 75% up... leaving only a 25% remainder on the dial to adjust the amount of gas you want to consider as dangerous and needing immediate attention. The unit has no indication of percentages or concentration levels, so its a blind guess as to what the battery wasting led lights and buzzers are trying to tell you. Obviously its alerting you to the presence of natural gas, which is good thing...But when zeroed in fresh air, the calibration dial will have very little room left for actual calibration. A slight touch of the wheel will send it into overload WHEN ITS OUTSIDE in fresh air. That is a flaw that needs correction. The battery cover also needs a redesign as it often requires a circus act to remove it.If the incessant buzzing doesn't drive you crazy, then the 10-12 minutes of battery life will. This thing eats AAA batteries and needs three at a time to work properly. I can't validate the effectiveness of the unit once the low battery light comes on. It will still work and detect but I can't speak to the level of accuracy at that point.After 10 weeks of fairly decent usage... maybe a total of 5 hours, the unit is showing signs of breaking down. It started to give false readings with regularity. Its tone has changed and that tone has often become shaking and erratic and I'm starting to loose confidence. I still have a bunch off interior walls that I'm sniffing and will need to purchase a higher end unit to get me through my project. For this reason... failing sensitivity after 5 hours... I gave the unit 3 stars.Lastly... if you're going to use this thing only once a month for 5 minutes, I think its a good value for the average homeowner. If however you're drilling into walls and ceilings, and tracing gas lines thru your structure, I'd start with one of the more professional models offered on the internet.
