sf 6 Leak Detection wika

gaz sf6 gas - WIKA USA. The importance of monitoring sf6 gas gas leaks and emissions Although SF 6 is non-toxic, any escaped gas can displace oxygen in the air and lead to asphyxiation in closed spaces. It is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the atmosphere. Get PriceGet price

Sulfur hexafluoride - Wikipedia

The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium- and high-voltage switchgear. Uses in magnesium, aluminum, and electronics manufacturing also hastened atmospheric growth.Get price
