Highly sensitive sulfur hexafluoride measurement tools manual

IDENTIFICATION: Sulfur hexafluoride is a colorless, odorless and tasteless gas. It can also be a liquid at extremely low temperatures. It is moderately soluble in water. It is a Greenhouse Gas which contributes to climate change. Sulfur hexafluoride is more effective at trapping heat than carbon dioxide. The Global Warming Potential of sulfur hexafluoride is quite high (25,000; the Global Warming Potential of CO2 is 1) and amongst the highest of all chemicals.
