Highly sensitive IR SF6 Components Detection

SF6 Gas Detection: Sulfur Hexafluoride (SF6) is a gas commonly used as an insulator in the electrical utilities industry, typically in high voltage switchgear and transformers. Although very useful, it is a highly potent greenhouse gas, being several thousand times worse than CO2 in terms of environmental impact.
