Natural Gas Leak Detector Pen by General Tools | #PNG2000A

Amazon Customer: It works but you have to get the tool directly on the joint leaking. Spray bubbles are still more reliable than this I believe.

Tim White: Seemed to work first couple tries. We repair and rebuild appliances. We had a gas stove with a broken line and you could smell the gas immediately. As we were repairing the line I got unit out and it wouldn't detect anything!! We even put it over an open gas line and nothing. We changed batteries and still nothing. We saw comments about similar issues and they claimed that cleaning tip helped.. we did this and still nothing.. I was so disgusted I threw it in trash. I've gone back to soapy water for checking lines and connections. I'd like to get same type of unit around same price but I'm very skeptical now.

Amazon Customer: I've been in the heating trade for 35 years now & have seen a lot of examples of "tradeline" gas leak detectors. There were always the gas utility testers that were also far too expensive to purchase & keep calibrated; the first break from that that I recall was the Tif8800, which was reasonably priced and calibrated in the field. Setting aside the sucky nature of its rechargeable batteries, if calibrated by its instructions it was wildly oversensitive & could literally be tripped by breathing into the sensor. Last time I checked, I wasn't exhaling methane.

Fast forward to my recent need for a leak detector, I decided to get a couple of different "current tradeline" options, and a couple of cheap Amazon alternatives. One of them totally sucked (it mimicked the tif8800, unsurprisingly). This is the other one - within a day, I found 3 gas leaks that I did not smell (all of which were trivially corrected). Within a week I had found 6 total. I recommended to my boss that they get one of these for every field worker, and I suspect it'll happen because of the price.

This is not an LEL detector, far from it. We don't carry LEL detectors, can't...

Buddy: I’m an HVAC tech. This time of year we start focusing on heat which means a lot of natural gas furnaces but all year round, to a lesser degree, we interact with natural gas (water heaters, gas logs, gas lines for remodels & new construction, even the gas to the furnace assuming the customer’s gas is still on). But this time of year there are a lot of heat maintenances (preventative maintenance visits) and heat related service calls. I have had a chance to use this detector dozens & dozens of times already.

First, the construction of it doesn’t seem extremely robust but, for what it is, I wasn’t extremely worried about that as long as it works. It does work but you have to understand what it is. This detector picks up on, if I recall correctly, 200 ppm (parts per million) as a low alert and 500 ppm as a high alert. It changes tone & displays a yellow light for a low alert & changes tone again & displays a red light for a high alert.

That’s not very sensitive. For comparison, a high quality combustible gas detector picks up on levels at least as low as 50 ppm. Real world, what that means is this one basically picks up on...

Hazel: I had a leak in the dual propane regulator on my travel trailer/RV. I was able to quickly confirm where the leak was and check to make sure that I had repaired the problem correctly. The tool worked great. Good price on this item also. You do have to be able to touch the tool to where you want to check for leaks. It will not work several inches away unless you have a really bad leak and the vapors collect in an I closed space.
