Gas density monitors and gas density sensors for insulating gas and

Trafag gas monitoring devices measure the gas density directly, i.e. sf 6 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.sf 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring thegaz sf6 gas density.Get price

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price
