Rated 4.5 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by No more soap bubbles for me I bought this gas leak detector to check pipe fittings on a gas water heater and a kitchen stove I had been working on. Up to now I have used the soapy water method which has always worked well but can be messy. I decided to use both methods this time to see how they compare. Both methods showed the same results even to the point of the detector showing a minor leak where there were small soap bubbles! I feel confident that the detector will be all I will need in the future. September 10, 2016
Rated 4.0 out of 5.0 by Seems to work as advertised Recently used this to test a gas connection for a water heater I changed out. Used this and the old soapy water test. This pen detected no leaks, soapy water confirmed this. I tried it on my portable grill just to make sure it worked. It did detect gas, so I assume it would detect a gas leak as well. I am going to continue to use this along with soapy water just for peace of mind but it appears as if it works fine. December 10, 2014
Rated 4.0 out of 5.0 by Portable Gas Leak Detector This product works as claimed in detecting gas leaks. I utilized it in an area I was certain of a leak and this was able to detect it right away. I like that this product is portable and easy to use. It gives me a bit of peace of mind that if needed, it would help me detect where a problem might be. December 8, 2014
Rated 5.0 out of 5.0 by Great For That Extra Precaution This tool is perfect for use in HVAC work as well as appliance maintenance. Light weight, easy to use and easy to store. Very nice addition to our other tools! December 11, 2014
Rated 5.0 out of 5.0 by Works well Very easy to use. Just remember to turn it on someplace with fresh air like outdoors as it calibrates itself when you first turn it on. Tested it with natural gas, propane and even a small disposable lighter. Detected the presence of gas quickly. December 13, 2014
Rated 4.0 out of 5.0 by Works well, but has limitations and may not be intuitive I struggled with how to rate this detector. It works well and seems to have similar features to its competition, but this class of meter has some limitations you need to be aware of (and isn't quite what I was expecting).. First off, I believe this meter performs well for anything it claims to do. The instructions that come with it are written by someone with good English and are easy to understand (which is not something I can say about many products these days). It comes with two AA batteries that were easy to install. I had no problems using it following the directions. It's rated to detect Methane, Propane, and Butane. Now for some of my concerns: First off, I would not describe this as intuitive to use. There are no instructions on the unit itself to explain what the various tones are or what the LEDs on it mean. Also, you have to power this on away from any gas to calibrate it. None of this is a problem if you read the easy-to-follow direction booklet, but in a age where people think they should be able to use stuff without reading instructions (or where they lose the instructions), someone could easily misuse or misunderstand this. It's also important to know that you have very little resolution on this meter. Basically you have 3 values: gas not detected (green LED), some gas detected (yellow LED: 20-50% Lower Explosive Limit = LEL), and high gas detected (red LED, >50% LEL). So if you are looking for a meter to give you detailed stronger/weaker readings for trying to find a leak, this probably isn't it. Finally, I worry a bit about is sensitivity: as noted above in the LED colors, this meter isn't set to trigger until it reaches 20% LEL (Lower Explosive Limit). In playing with my propane-powered stove, I can smell the propane with my nose before this meter detects it, much in the same way you can probably smell smoke before your smoke detector goes off. I believe if you smell gas this may help you pinpoint where the leak is coming from, but if you are depending on it to tell you that you have a gas leak, it may not have the sensitivity you want. (By the way, 100% LEL is the point where a flame/spark could cause an explosion, so you definitely want to detect and fix any leaks well before you reach that level.) So if you are comfortable with the feature set, I have no issues recommending this detector at its price point. But if you actually wanted a digital meter with a readout giving you strengths, or something sensitive to detect low gas levels (lower than your nose will detect), you may want to look for a different style of meter.
