no such thing
All gas detectors will alert when a petroleum based pipe dope is used. For gas you need to use a product without petroleum. There are a lot of Teflon based dopes out there but I've been using Megaloc for years with great results. Also a heads up, typing in caps is bad on-line etiquette, it's considered yelling.0 -
Gas Detectors
A gas detector will show the general idea of the location of a leak . I have one sitting in the truck for years ... I find a good bubble solution like Big Blue with show you the slightest leak ... Far better then soapy water...There was an error rendering this rich post.

Gas detectors are designed
to be used as a safety device to measure percent of gas in an environment. With natural gas the Upper (14.5 % gas) and Lower explosive limits (4.5% gas) are measurable with the detector. Or for LP it is 2.15 to 9.6%. Any reading above 2% you should evacuate the building and call the utility or propane company. NEVER enter a building were you smell gas unless you can determine % of gas with a good detector. Any thing less than 2% proceed with caution ventilating the area and make sure all sources of ignition are secure. An easy way to remember is above 2% you evacuate below you ventilate.
They are not the best for pinpointing gas leaks. Better to either do a test using the test dial on the meter with all pilots shut off to show that there actually is a leak.There would be movement of the 1/2 foot test dial. Or another method is by using a U gauge (manometer) and see if there is a pressure drop. To finally pinpoint leaks is to use non-corrosive soap and water.0 -
