UEi Combustible Gas Leak Detector - CD100A - Test Instruments

Monica JordanMonica Jordan: All the reviews said this was one of the best combustible gas leak detector.

It works. But, the sensitively is low…

I have a cheap gas detector and it really is bad…

This one detects and within a few seconds when removed from the source “clears” and stops alerting APPROXIMATELY.

So, I do like that. I only give 3 stars because the distance from the leak source is only a few inches and has to be exposed for a second or two.

Meaning, you have to inch along a potential leak area SLOWLY to hope and find a leak.

I’ll try it out and hope this helps me figure out where the leak is, from the 40 foot line that it can be in…

Thanks for reading.

PS uses a 9volt battery. Mine came with one, but I bought a used one. So I’m not sure if it comes with one originally…

Buddy: 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...

Tripod: 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.

A. Jain: 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...
