973-sf 6 Gas Analyzer | Sulfr hexafluoride Humidity Purity Test |Testnordic.com

Description. 973-insulating gas gas analyzer used for simultaneous measurement of humidity, SF 6 purity and SO 2 concentration. Pure SF 6 is the standard filling within GIS, but over time gas compartments become contaminated with water vapor (H 2 O) through permeation and by desorption from internal materials. Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur andGet price
