Sulfur hexafluoride, gas weighs 0.00641 gram per cubic centimeter or 6.41 kilogram per cubic meter, i.e. density of sulfur hexafluoride, gas is equal to 6.41 kg/m³. In Imperial or US customary measurement system, the density is equal to 0.4 pound per cubic foot [lb/ft³], or 0.003705 ounce per cubic inch [oz/inch³] .

Description. 973-SF6 gas analyzer used for simultaneous measurement of humidity, SF 6 purity and SO 2 concentration. Pure SF 6 is the standard filling within GIS, but over time gas compartments become contaminated with water vapor (H 2 O) through permeation and by desorption from internal materials. Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy

Trafag gas monitoring devices measure the gas density directly, i.e. SF6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF6 Gas Density Sensors, or by combining both principles, i.e.SF6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF6 gas density.
