Gas Sensors Methane

Methane is a gas produced by a group of colonic anaerobes. All methane produced by human beings is a metabolic product of intestinal bacteria, and about 50% of it is excreted. Methane is also found below ground and under the sea floor. It is emitted during production and transport of coal, natural gas, and oil, as well as from lifestock. Methane makes up roughly 10% of Greenhouse Gas ...

Safety Scan USA | Residential Methane Gas Detector

Our Methane Detector will not detect anything other than methane so you will get no False Positives. The importance of methane is quite different from CO2 or Smoke. Accumulation of methane undetected is a potential bomb, that is why we have a 120Volt wired (with battery backup) 24H fully connected Unit. There will be no 2am alarms going off notifying you that the batteries need to be changed ...
