Methane Gas Detectors
Methane (CH₄) is a colourless, odourless, and highly flammable gas that is the main component of natural gas. It is lighter than air and can form explosive mixtures if it accumulates in confined spaces.
Methane is commonly found in natural gas pipelines, oil and gas production, landfill sites, wastewater treatment plants, and coal mines, as well as being produced by organic decomposition.
To detect methane, gas detectors typically use LEL (Lower Explosive Limit) sensors, which monitor how close the concentration is to its explosive threshold, allowing for early warning before dangerous levels are reached. Rockall Safety offers a range of methane detectors including the Crowcon Xgard and the Crowcon UNOIQ.
