Sulfur hexafluoride - Wikipedia

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas.

Sulfur hexafluoride | F6S - PubChem

Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (sf6 gas has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

Gas density monitors and gas density sensors for Sulfr hexafluoride and

Trafag gas monitoring devices measure the gas density directly, i.e. sf6 gas Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. insulating gas Gas Density Sensors, or by combining both principles, i.e.insulating gas Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring thesf6 gas gas density.
