10/10 would buy again

Exactly as described. Quick shipping. Works great. Definitely recommend this meter.

I am an HVAC service tech. This combustible gas detector is a professional quality tool, it works exceedingly well and is unbelievably sensitive. It’s sold at a number of HVAC parts houses. It detects basically any combustible gas at levels at least as low as 50 ppm (parts per million).It is not auto-zeroing which I actually prefer. That means it doesn’t automatically desensitize itself with exposure to combustible gas. You can adjust the sensitivity yourself as needed meaning you can decrease sensitivity as the area is saturated with gas and you zero in on the leak and at ANY point you can crank the sensitivity back up without having to wait a long time or restart the detector & move back outside. It also means when you initially start it up you have to adjust it to the required baseline. Give it a minute or two to warm up & adjust it to a few clicks per second.I’ve used this detector at least 8 or 10 times so far. It pick up instantly with no delay & recovers very quickly. On both accounts it is MUCH better than my previous detector. It is also INSANELY sensitive and I mean CRAZY sensitive. A funny experiment, it’s so sensitive that it will detect methane when you put it close to anyone’s rear end and that’s when they are not passing gas.The point being, don’t let the extreme sensitivity of this detector drive you crazy. It WILL pick up on the most insanely small “leaks”. I would suggest confirming all leaks found by this detector with a bubble solution. Not because of the reliability of the detector but because the leak could be so small as to be insignificant. Gas lines typically hold no more than 2-3 PSI of gas (on your side of the gas meter). They are tested & passed at 10 PSI. By their nature, gas lines are not exceptionally tight. Most gas lines, if pumped up to 10 PSI & left for a week, will have lost a good amount of pressure. My point being, if you find a leak with the gas detector but it won’t show up with a bubble solution PROPERLY ADMINISTERED it’s too small to worry about. You could search the entire gas line on a small old house & probably find over a dozen “leaks” that small and it could still pass the pressure test.Here’s another pointer, sometimes it’s normal to smell a little gas. What? That can’t be right? Your gas meter has a pressure relief on it. It will, from time to time, purge a little gas, especially when gas appliances are turning on & off. Just because you smell gas when you walk by the meter doesn’t mean there’s a problem. When your gas furnace shuts off the gas valve closes and the gas inside the distributor equalizes to the ambient pressure, but it’s inside an enclosed tube so not every last bit gets blown out of the flue by the inducer motor. Everything shuts down and over minutes that tiny amount of gas slowly dissipates. If you pull the door off the burner compartment of your furnace at the right time you’ll smell gas. This detector will pick up on it. It’ll hit big right at the orifices where the gas comes out. That doesn’t mean there’s anything wrong.What I’m getting at is, be safe with gas but understand just how sensitive this detector is and if you’re not sure what is or isn’t normal call a professional. The professional would be more than happy to have this detector in his arsenal of tools.

Works awesome

Excellent tester. I use it on my camper propain system. Easy to use and very sensitive. Highly recommended.

I just have had this product for a couple weeks now. I started smelling a gas smell in the basement, so I purchased this and it came quickly in 2 days. When I started using testing for gas, it started beeping more and more, until I found the leak at the manifold. I then got soap and water , and sprayed it to the suspect location and sure enough it started to bubble. I called the gas company and they came and changed the manifold and now no more smell. The only thing that would have probably made this better would be a numerical readout, but those ones probably cost thousands of dollars and also a small case for it. For the price, this is a must for a homeowner to have. I also own a RV and this can help determine if I have a propane leak. Awesome product.

When I received the detector, I tried to turn the switch on, and it only spun, did not click on or off. Also, there were no instructions that come with the device, just a bubble pack cardboard advertising a few features. Since I need this, and it has been rated higher, I sent this one back to Amazon for a refund, and ordered a new one. I am hoping that I just received the bad 1 in 1,000 on the first go-around, and the next one works as advertised.[Update - 1 week later] I did receive the new detector, and it was in proper working order. The unit had a battery already installed, and also included instructions. This makes me conclude that the first unit I received was someone else's return, and they simply put it back on the shelf.Now, as far as the operation and my observations using this unit, it appears to be pretty good. I was able to identify the location of a propane leak in my RV, which I verified using the soapy water test to see where the bubbles formed. I was able to disassemble the connection, add the proper gas (yellow Teflon) tape, and determine the leak was no longer present. Using the wand detector, I quickly verified the integrity of the rest of the connections.I did notice, it is so sensitive, that when I hold the sniffer tip in my hand, my personal gases make the detector tick faster. Also, just breathing on the tip does the same thing. Hold it near some plastics also has the same affect. Overall, I am changing the rating from 1 to 4 stars. This is for the equipment. Amazon disappointed me by sending me a used item, but they were very fast with crediting my account for the return, which UPS picked up from my house the next day, at no cost to me.

When I needed to find a gas leak in a cluttered basement, I rapidly concluded that the traditional approach of coating the pipe joints with a soap and water solution and looking for bubbles would take a very long time and create a mess. With costs for a plumber running to $100 per hour, a gas detector quickly began to look like a good investment. The UEi CD100A seemed just the ticket -- simple, inexpensive, and reasonably rugged. It turned out to be all of those things.Operation is simple -- just turn the detector on (in clean air), wait for a minute or two, adjust the audible tick to a slow but steady rate, then move around until the tick rate increases. The faster the tick rate, the higher the gas concentration. (Imagine a Geiger counter that detects gas instead of radiation...) Just move the sensor along the piping until you find where the tick rate is highest, and you've found the leak.The price is very reasonable for an electronic instrument of this quality. Most detectors of similar quality are more expensive.The device is also reasonably durable. The gooseneck is a bit delicate (especially where it joins the body of the instrument), but this is a complex electronic device, not a hammer. If you treat it with a bit of care it should last a long time, though the sensor module will likely need to be replaced every few years. (This is just the nature of electronic gas sensors, and isn't a weakness of this particular device.)It's worth noting that this is a leak detector, not a gas level monitor. It is designed for plumbers, appliance technicians and DIYers who need to locate a gas leak and/or to verify that there are no leaks after working on gas plumbing or appliances. It's not intended as a continuous duty gas safety monitor. There's no readout of gas level in PPM, so there's no way to determine the actual level of gas present. If you need to locate a leaking fitting in a gas line, this is the perfect device. If you're looking for a gas monitor for your basement, or for OSHA compliance, this device isn't what you need. As long as you're not expecting the device to do things that it's not designed to do, it's a great instrument.Pros: simple to use; inexpensive; reasonably durable; compactCons: gooseneck not quite as durable as it could be
