gaz sf6 Gas Analysis - Qrometric

For Sulfr hexafluoride filled gas compartments, Sulfr hexafluoride in accordance with either IEC 60376 or IEC 60480 is used. In order to prevent condensation, the maximum allowable water content is defined by a dew-point no higher than – 5 °C. Gas compartment fill specifications typically define much lower dew points (manufacturer dependent).
