745 reviewsPlace alarm near ceiling for natural gas and near floor for propane/butane. Testing/Tips:-Due to added odorants, people can often begin smelling a gas leak at 1% LEL whereas available retail gas alarms set an alarm threshold of 5%-25% LEL to avoid frequent false alarms. Do not be alarmed if you smell gas before the device alarms.

A leak as small as 2.5 gallons per day can be detected without service interruption or excavation. And finally, our HeliTec ® helium leak detection service quickly locates leaks in buried pipelines as well as plant piping and systems. The method uses a helium tracer in a gas, usually with nitrogen as a carrier gas, and a sensitive helium detector.
