hitachi SF6 room Equipment

SF6 is an artificially manufactured gas molecule in which six fluorine atoms are arranged around one sulfur atom. SF6 is an effective power equipment insulator–but can be dangerous when it leaks into the environment. Typical gas monitoring uses temperature and pressure to calculate the temperature-compensated pressure.
