Trafag sulphur hexafluoride process for gas measurement

Additionally, if registrants select 'other' as a unit of measure for pressure, the measurement conditions (and therefore the study results) cannot be processed in the Brief Profile. Summary Melting/freezing point at 101 325 Pa provides information on the substance melting/freezing point in °C at a pressure of 101 325 Pa.

  • Gas density of SF6 and other gases - Trafag AG

    Sulphur hexafluoride (SF 6) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc-quenching) properties. It thus makes it possible to set-up complex and safe ­power distribution systems even in large cities. The insulation strength depends basically on the gas density.

  • Ventilation Measurements Using Sulfur Hexafluoride (SF6

    Mar 20, 2019 · Sulfur Hexafluoride a Common Tracer Gas Used For Ventilation Studies Sulfur Hexafluoride , also known as SF6, is by far the most common tracer gas used for ventilation studies. The primary reason is that it is easy to detect at low concentrations—even in the parts per billion (ppb) or parts per trillion (ppt) range and has very low toxicity.

    Sulfur hexafluoride is also routinely used as a tracer gas in laboratory fume hood containment testing. The gas is used in the final stage of ASHRAE 110 fume hood qualification. A plume of gas is generated inside of the fume hood and a battery of tests are performed while a gas analyzer arranged outside of the hood samples for SF 6 to verify the containment properties of the fume hood.
