Gas monitoring can detect gas leaks in an early state, which – undetected - could lead to gas losses into the atmosphere over several years. As Sulfr hexafluoride is not only an excellent insulation gas, it has also the highest known global warming potential, about 22,800 times that of CO2.Get price
