Did not last for me. Quit at 14 months. UEI wanted $100 to fix.

August 25, 2015

Verified Purchase

Hi, I'm a veteran home inspector. I treat my tools well. I liked this detector. Reminded me a lot of the old tif8800. Worked just like it, and worked as well. The nice thing was, I could simply use a 9volt battery in this one and didn't have to buy special batteries like the Tif. Was happy with it for 14 months until it quit working. The wheel on it came loose and I could no longer adjust the thing or turn it off. Called UEI -- who typically offer good service -- Found out it was past warranty by a little and then learned that it would cost just a little over $100 to have them fix it + shipping. $100 goes a long way toward a new one and so decided to junk this one instead of sinking another $100 into it. But since I hate to just throw things away, I opened it up and was able to fix it myself. It turns out the wheel comes loose from the control. I used blue loctite on the screw and am hoping it will hold. Bottom line -- will shop somewhere else for a gas detector next time. Would appreciate it if UEI would stand behind this product but they didn't -- a better design on the wheel and holding screw is needed.

If you're wondering if you need something like this, you should just order it.

January 30, 2015

Verified Purchase

I originally bought this to help troubleshoot a propane stove in my Airstream, which I suspected was leaking. There was just a touch of a long-lingering gas-like odor, but many of the gas connections were too hard to reach to try testing with water and soap. After reading the reviews, and cringing at the price, I finally ordered one.

I was excited when it arrived. My foray into serious, committed gas detecting had begun! The unit has a bit of heft, and feels well made. And, it's super easy to use. After inserting a battery you simply spin the dial to turn it on and then increase the sensitivity, until it starts "clicking" repetitively in clean air. Extend the flexible probe, and start poking at things you think might be leaking leaking combustible gas (i.e. propane). If it finds even a little bit of stray gas, it starts clicking faster. If it finds a major gas leak, it clicks so fast that it sounds like it's buzzing. Think Geiger counter.

So, I started probing around near my gas stove, where I thought the leak might be. Nothing. Because of the long probe, it's easy to press it up against each individual fitting to see if it's tight, or leaking. I pressed it against each fitting going to the stove. Still nothing. Could my dual electric/propane refrigerator be leaking? I checked each connection on that, too. Still nothing. Maybe the detector wasn't working? I turned on my gas oven, without the pilot being lit, and held the probe near the gas outlet. The detector immediately went crazy. So, it was working. To make a long story short, there was no leak. It turns out that my old carpet was just really smelly. No, not kidding. But I wouldn't have known without the detector.

So, it turns out that a sensitive detector is useful not just for finding gas leaks, but also for determining that there really is no leak. But, my detector hasn't been sitting idle. In the meantime, I've used it to check every visible gas connection in my house for leaks. It's helped me pinpoint a propane leak in my camper shell. I just used it to check every new propane joint after having to replace my dual propane tank automatic changeover regulator after it failed, and it almost instantly found a couple of leaks which allowed me to quickly fix the bad connections. And, it even helped me troubleshoot a loose gas connection in a house I sold recently, after the home inspector flagged a gas leak. Without this unit, I would have had to call a contractor to trace it. Instead, I was able to quickly find the leak and fix it myself, which turned out to be nothing other than a loose connection without the sealant which it should have had. That alone more than paid for this unit. If you hold this up to someone's mouth, you can even tell if they've been drinking. Don't ask me how I know.

Not trying to sound like I'm an expert here. I'm really just a regular DIY kind of guy that likes to work on relatively easy stuff. But, if you have an RV, or a house with natural gas, or do any kind of work whatsoever with propane, or natural gas, or RV systems, this awesome tool can give you a "sixth sense" to find that (possible) gas leak. It helps you quickly determine (1) is there a leak? (2) if there is, exactly where it is, and (3) based on #2, the added ability to help determine if it's something you can fix yourself easily, or if it's maybe time to call in the real experts.

A simple and effective tool for locating gas leaks

January 23, 2014

Verified Purchase

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; compact
Cons: gooseneck not quite as durable as it could be
