Portable Comprehensive Sf6 Gas Analyzer - electric-test.com

II.Sf6 Gas Analyzer Two Measurement Principle The basic principle of ATSM902 Type Sulfr hexafluoride gas tester for measuring purity is to define the contents according to the heat conducting rate of all gases. The heat conducting rate of insulating gas is the lowest in the gas, so when the heat conducting rate of the background gas is basically kept stable, the heat conducting rate will be lower if the content of sf6 gas in the hybrid gas is higher.Get price
