It therefore has a cumulative impact on climate, like CO2 and N2O, and a relatively small amount of gaz sf6 can have a significant long-term impact. The atmospheric sf 6 abundance was estimated to be 10.0 ppt in 2019, up from 7.0 ppt in 2011 (IPCC 2021).

Description. The SF 6 gas analysis instrument model GA11 is an innovative and inexpensive instrument for determining the SF 6 gas quality. Model GA11 can measure the concentration of up to seven parameters. Design. A clearly arranged menu structure and a 7" colour touchscreen allow for intuitive operation.

A method for detecting loss of insulating gas gas from electrical utility apparatus determines a molar ratio of gas in a container at an initial time and of gas in the container at a subsequent time. Measurement of temperature is determined by averaging ambient temperature
