973-gaz sf6 Gas Analyzer - MBW Calibration AG

Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur and fluorine from SF 6 to form decomposition by-products. These include sulfur dioxide (SO 2) and hydrofluoric acid (HF) that are corrosive to the internal components of gas compartments.Get price
