Product Overview

The PNG1 Gas Detector Pen detects natural gas, compressed natural gas, ch4, methane, propane and butane, liquid natural gas (LNG), liquid petroleum gas (LPG) to locate leaks in pipes, valves and fittings. This essential tool is packed with features such as audible and visible annunciation and Catalytic combustion sensor. The high sensitivity of the unit to natural gas (methane) and LPG (propane) and affordability make it ideal for the technician, Do-It-Yourselfer or homeowner.

does this measure natural gas leaks from a gas furnace?Bernie

does this measure natural gas leaks from a gas furnace?Bernie
Asked by: Bernie
yes it will but expect to hold the detector near possible/ suspected leaks locations (joint connectors, flex lines, etc.) for about 30- 40 seconds before moving and checking the next location. also very important - turn the unit on in known fresh area like outdoors and wait for the indicators to say it is ready to use (remember to read the directions) then go inside or near where you want to check.

Does this pen work to detect Hydrogen Sulfide leaks?

Asked by: Michelle
I do not know. Hydrogen sulfide has a different composition than methane gas. H2S has a rotten-egg smell and you would be able to note its presence immediately without a sensor. Although both are flammable gases hydrogen sulfide is flammable at concentrations a lot higher than methane gas. The danger with H2S is that at low concentrations it is highly toxic to humans, sometimes causing death. If you smell a rotten-egg smell ventilate the room and exit immediately!

Does this detect Freon leaks

Asked by: Duece
Have never used it to check for Freon leaks. I have always used soap solution to check for Freon leaks.

Combustible Gas Leak Detector Pen with Auto-Calibration Function is rated 4.4 out of 5 by 11.
Rated 2 out of 5 by from product is ok i does work as designed, however it tested a few times and it takes up to several m... product is ok i does work as designed, however it tested a few times and it takes up to several minutes sometimes to detect the actual leak. i tested on a gas stove without lighting , after turning the unit and waiting for the detector to indicate that it is ready to use i then turn on the gas stove with no flame and wait... and wait.... and wait.... finally the detector sounds off. (DANGER!) all the lights lite up. i tried this several times both on low burner and high burner. sometimes the detector worked within a reasonable time frame other times it took almost 30-40 seconds and i can smell the gas already. but for the price i guess it is ok just be sure to be patient and check for leaks several times leaving the unit in place for at least 30 seconds or so where you would might expect a gas leak could occur. i.e. connection points and along flexible lines.

Rated 5 out of 5 by from seemed to work great. after testing on my gas stove, left a burner on just a little bit. it picke... seemed to work great. after testing on my gas stove, left a burner on just a little bit. it picked it up right away. Then went and checked all gas fittings, no leaks. Great Then came the real test I Farted , put the leak detector near my butt and off it went all lights flashing.LOL . This thing works great .

Rated 4 out of 5 by from Good Works as advertised. Calibration a little hard to do. Not clear if you have to calibrate before each use.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
