May 20, 2020SF6 purity is typically measured using conductivity or speed of sound measurement techniques. Impurities that reduce the percentage of SF6 by volume are mainly handling the gas, the filling and emptying of compartments that may inadvertently incorporate air and water vapor due to erroneous operation, incomplete evacuation of pipes and vessels, leaks in connections, and seal surfaces. Systems are often used in field density meters.

But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earth's atmosphere. According to the Intergovernmental Panel on Climate Change IPCC, abandoning SF 6 completely could contribute 1.5 percent to
